If you are new to custom flexible packaging,
this is the most comprehensive guide you can follow.
Here’s the thing:
Many of our most successful customers started exactly where you are now.
So we thought:
Why not create an all-in-one complete guide to custom flexible packaging for everyone?
That way, even beginners can quickly learn everything they need to know when they want to customize their flexible packaging.
So that’s exactly why we’ve prepared this guide for you.
In this guide, I’ll walk you through the complete custom flexible packaging process,
step by step.
Even better,
These steps are all proven in real-world practice, so you can apply them with confidence.
What is flexible packaging?
Benefits of Flexible Packaging
Flexible packaging has 3 key advantages.
- Lightweight and space-saving
- Highly adaptable to various products
- Lower packaging and shipping costs
Best of all:
Flexible packaging doesn’t mean hurting the environment.
Today, there are sustainable options available for you brand.
(more on that later…)
How Laminated Structures Work?
1. What a “Laminated Structure” Really Means
You might think a pouch is just one simple layer.
But in reality, most flexible packaging combines 2 or more films into one laminated structure.
That is why you often hear the term “laminated packaging”.
Here is the reason:
Different films do different jobs, and lamination lets them work together as one material.
In a typical structure, layers serve 3 main functions from outside to inside:
- The outer layer is the printing layer.
This is where your design lives and where surface durability begins.
- The middle layer is the barrier layer.
It blocks moisture, oxygen, and light, and often adds structural strength to the packaging.
The middle layer is typically made from a single barrier film, but it can also consist of 2 films laminated together, or in some cases be omitted entirely, depending on the specific barrier requirements of the product. - The inner layer is the heat seal layer.
This layer touches your product and keeps the bag sealed.
2. Common Structures & Their Applications
Let’s use mylar bags as an example.
I’ll break down 4 common structures of mylar bags to show you how packaging layers actually work.
a) High-Barrier Type (Most Popular)
Typical Structure: PET or BOPP / Metallized PET (VMPET) / PE or CPP
Outer layer (PET/BOPP): For printing and adding stiffness.
Middle layer (VMPET): Provides excellent barrier against oxygen, moisture, and light, also boosts stiffness
Inner layer (PE/CPP): Heat-sealable layer for strong seals, adds flexibility, and is safe for direct food contact
Best for: Candy, snacks, cannabis, protein powder, seasonings
Highlights: Most widely used, balanced performance, Cost: Medium
b) Ultra High-Barrier Type (Long Shelf Life)
Typical Structure: PET or BOPP / Aluminum Foil (AL) / PE or CPP
Compared to the first type, metallized PET is replaced with pure aluminum foil. This gives your bag nearly 100% barrier against oxygen, moisture, light, and odor.
Best for: Coffee, pet treats, hemp, cannabis, and other sensitive products
Highlights: Extremely long shelf life Cost: Higher
c) Standard-Barrier Type (Transparent & Economical)
Typical Structure: PET or BOPP / PE or CPP
This structure has one fewer layer than the previous two.
The outer PET/BOPP handles both printing and basic barrier.
Since there’s no metal layer, the bag is fully transparent.
Best for: Short-shelf-life items – bread, baked goods, salads, seasonings, also non-food items like daily care products
Highlights: Clear, simple, cost-effective Cost: Lower
d) Transparent High-Barrier Type
Typical Structure: PET or BOPP or PE / EVOH or BOPP Alox or PET Alox / PE or CPP
Instead of metallized or aluminum layers, the middle layer is a transparent high-barrier material.
This structure gives you strong barrier + visibility at the same time.
Best for: Pet food, meat, nuts, and other products that need to show contents while staying fresh
Highlights: Transparent + high-barrier Cost: Higher
Here’s the bottom line:
Different layer combinations exist to protect different products.
Once you understand how these structures work, you won’t judge packaging just by how it looks.
That’s how you make smarter, more reliable packaging decisions.
If you already have experience with custom packaging, and want to explore more film options for advanced customization.
For a deeper dive into advanced film options, refer to: Flexible Packaging Technical Material Guidance.
Note: If this is your first time customizing packaging, like most people, don’t feel overwhelmed by the information above.
You only need to describe your product and its packaging requirements.
An experienced packaging manufacturer like Pouching can recommend the right materials and laminate structure for your products.
3. What to Ask Before You Approve Any Structure
You do not need technical expertise, you just need to ask the right questions.
Here are 3 questions you can use to validate any proposed structure.
- Most important: Has this structure been successfully used for similar products?
If yes, ask for real examples or case references. Real-world experience matters more than theory.
- Why does this structure fit our product and expected shelf life?
Make them explain the logic clearly, not just recommend it. - Are there any potential risks or limitations I should be aware of?
Every structure has trade-offs. You need to know them before production begins.
Once the answers truly make sense to you, approving the structure becomes much easier.
How to Describe Your Packaging Needs
This step matters more than you think.
It sets the foundation for your entire packaging project.
Here’s the thing:
Your supplier does not start with packaging.
They start with your product.
You describe your product.
An experienced manufacturer translates that into packaging performance requirements.
So what should you tell them?
It’s simple.
Use the checklist below and you will cover almost everything that matters.
Product Information Checklist
What exactly is your product?
Be specific. Powder, liquid, solid, food, supplement, pet product, chemical, or something else.
What environmental factors must your product avoid?
Think moisture, oxygen, light, air exposure, throwing, stacking, squeezing, friction, compression, and odor contamination.
Does your product contain oil, moisture, strong odors, chemical components, or any sharp parts/edges?
This directly affects material choice, sealing performance, and whether puncture-resistant material is required.
Do you need child-resistant packaging?
This is critical for regulated or high-risk products.
What is your product turnover time and expected shelf life?
A longer shelf life means higher barrier requirements.
What are the highest and lowest temperatures during filling and storage?
Hot fill, cold storage, or room temperature only?
Will your packaging face stacking, pressure, or drops during shipping?
Picture cartons piled high in a warehouse or bouncing in transit.
Are you currently using packaging? What needs improvement?
Leaks, weak seals, poor appearance, or high cost?
How will your product be filled?
Manual filling, semi-automatic, or fully automatic machines can affect bag structure and tolerance.
Do you have compliance requirements?
Different markets may require specific certifications, or labeling standards.
Do you need sustainable packaging?
There are different sustainable packaging options, recyclable, compostable, and post-consumer recycled, each with its own pros and cons.
For more details, you can read: The Ultimate Guide to Sustainable Packaging
If something important about your product is not on this list, include it anyway.
More clarity now prevents expensive mistakes later.
Customize Your Pouch: Type, Size, Look and Feel
In the previous chapter, you learned how to describe your packaging needs.
Now it is time to turn your idea into a real, physical bag.
This is where decisions become visible.
1. How to Choose the Right Pouch Type？
In theory, you can customize almost any pouch style.
Below are the most common pouch types.
Before we go further, one important note.
Rollstock vs Pre-Made Pouches
Rollstock is printed film supplied in rolls.
It does not arrive as a finished bag.
It must be formed, filled, and sealed using automatic packaging machines such as:
- Vertical Form Fill Seal (VFFS)
- Horizontal Flow Wrap machines
- Stick pack machines
- Sachet filling lines
Rollstock is ideal for high-speed, automated production.
Pre-made pouches, such as three-side seal, pillow pouches, stick packs, can be manually filled or semi-automatically filled.
If you do not own filling machinery, rollstock may increase your operational complexity.
Step 1: Consider Your Sales Channel
Your packaging does not exist in isolation. It lives in a selling environment.
In-Store Retail
Visit the store where your product will be displayed.
Is it placed on shelves or hung on hooks?
Is it at eye level, above eye level, or near the floor?
Physical position determines pouch type and design emphasis.
Stand-up pouches dominate shelf displays.
Hang holes work better for pegboard placements.
E-commerce
For online sales, you must consider not only how the package appears on your product page, but also how it performs in logistics.
Can it stack efficiently?
Is it compact and durable enough for shipping?
These factors directly impact fulfillment efficiency and overall logistics costs.
B2B or Inner Packaging
For bulk or internal use, practicality wins.
3-side seal pouches or pillow pouches are often the most efficient choices.
Step 2. Determine Your Filling Method
This is one of the most overlooked decisions.
If you use automatic filling machines, confirm pouch compatibility with your machine supplier or co-packer.
The wrong pouch type can significantly increase filling costs.
If you fill manually, you have more flexibility, but labor cost becomes your main variable.
Step 3. Evaluate Pouch Stability
Heavier products require stronger base support.
In general:
Stand-up pouches work well up to about 2kg.
Above 2kg, quad seal or flat bottom pouches provide better structure
Very light products under 100g may struggle to stand properly.
Small dimensions also limit stability.
As a practical guideline, if the pouch width is under 80mm and the bottom gusset is under 30mm, stand-up performance becomes unreliable.
Structure must match weight.
Step 4. Review Packaging Cost
Different pouch types require different manufacturing complexity.
From lowest to highest production cost (general ranking):
- Rollstock (flow wrap, stick pack, sachet)
- Lay flat pouch (three-side seal, pillow pouch)
- Stand-up pouch
- Shaped pouch (custom die-cut shapes)
- Quad seal pouch
- Flat bottom pouch
Complex sealing patterns and forming steps increase cost.
Step 5. Learn from Your Competitors
Your competitors are your best teachers.
Research their sales channels and the types of packaging they use.
Differentiation from competitors is the key to standing out.
However, overly unique packaging formats may conflict with existing customer perceptions.
High-quality design and printing are proven ways to grab customers’ attention.
Step 6. Consult Professional Support
You do not need to make every decision alone.
At Pouching, we help brands evaluate pouch types based on product, filling method, sales channel, and cost target.
Instead of guessing, you can leverage our experience to narrow down the most efficient solution.
2. How to Choose the Right Size?
Picking the perfect pouch size can feel tricky.
But it’s actually simple.
Follow these steps, and you’ll find the best fit for your product.
Step 1: Think about your product’s volume and weight.
You may have seen size charts based on weight alone.
But always look at volume first.
The same weight looks totally different in nuts, powder, or liquid.
If your product expands, like creams, leave extra space.
Step 2: Consider how easy it is to pour out
Smaller pouches work great for pourable products.
Bigger items need pouches with wider openings so customers can grab them easily.
Step 3: Adopt the “Output-Input” Method
You can find a suitable pouch size from other products.
Then pour your product into it.
This way, you can visually evaluate fill level, space, and how the pouch looks after filling.
This hands-on comparison gives you immediate clarity.
Once you have identified the right pouch, the next step is to measure its dimensions.
The process is straightforward.
Simply measure the height, width, and gusset if applicable.
You can also follow the step by step instructions in the video below, where we demonstrate exactly how to measure a pouch correctly.
Pro Tip
Always leave about 20% empty space.
It keeps your pouch from looking overstuffed and messy.
Step 5: Talk to the packaging pros
You don’t have to figure everything out alone.
At Pouching, our packaging specialists help you evaluate optimal dimensions based on product density, filling method, and structure.
A quick consultation can prevent expensive resizing later.
Unit Conversion Note:
Measurement units vary by country.
Refer to the Packaging Unit Conversion Tool for reference.
3. How your bag looks, feels, and performs
You already know your pouch’s shape and size.
But before you jump into design, you need to understand every customization option you have.
Each option is a unique element you can use to make your design stand out.
Let’s break it down into three key areas:
- Surface Finishes & Visual Effects
- Tactile Experience
- Functional Features That Boost User Experience
If you want to watch video demonstrations of all the processes below, you can watch here.
Keep reading.
a) Surface Finishes and Visual Effects
These directly influence visual perception.
Common options include:
- Gloss finish
- Matte finish
- Spot gloss
- Foil stamping
- Metallic effect
- Holographic effect
Used correctly, it elevates perceived value instantly.
b) Tactile Experience
This is how your bag feels in customers’ hands.
- Gloss finishes feel smooth and sleek.
- Matte finishes give you a soft, subtle friction.
- One premium choice is the soft touch matte.
Soft‑touch material feels smooth and rubbery, which is a top trend for high‑end brands.
3. Functional Features That Improve User Experience
These features change usability.
Options include:
- Hang hole
- Window
- Zipper
- Spout
- Degassing valve
- Tin tie
- Laser scoring for easy tear
- Variable barcode printing
Functional details often influence repeat purchase more than visual effects.
How to Design a Packaging That Sells
Great!
Now you already have a clear idea of your pouch.
Now let’s solve the design part.
This chapter shows you how to create a design that grabs attention and drives sales, even if you start at zero.
Let’s dive right in!
1. What is a dieline, and how to get one for free?
In flexible packaging and printing,
A dieline is the precise flat blueprint of your pouch or bag.
It defines the exact outline and layout before the film is converted into a finished package.
A dieline marks all critical production elements, including cut lines, seal areas, fold lines, bleed zones, and safe zones.
It ensures your artwork is correctly positioned, properly formatted, and ready for accurate manufacturing.
Sounds complicated?
No worry.
Cause you do not need to create a dieline yourself.
All you need to do is provide your pouch dimensions to your packaging supplier.
If you are unsure about the size, your supplier can recommend one based on your product.
A professional supplier will gladly create the dieline for you.
Want to make it even easier?
We have prepared template dielines, covering various pouch styles and label dielines.
You may also contact us to get a custom dieline.
2. How to find the right packaging designer?
You can never overstate how important packaging design is.
Customers judge with their eyes before they buy with their wallets.
That’s why finding a professional designer is so important.
The truth is,
Hiring a great designer doesn’t have to be complicated.
You just need to know what makes a good design and use that standard to find the right person.
I’ll guide you through 3 actionable steps to hire the perfect designer:
Step 1: Understand what defines good design.
You don’t need professional design skills.
All you need is an eye for good design.
The standard for good design is actually simple.
At its core, great packaging is designed to drive sales.
And after countless tests and proven results across the packaging design industry…
There’s one proven rule that great packaging all follows.
Stick to it, and you can easily judge any design.
It’s called the 4C Principles:
- Clarity
Your packaging clearly shows the product, key benefits, and how to use it at a single glance.
It cuts down decision friction for shoppers.
Real-world example:
Use larger, bolder fonts for key selling points to create strong visual contrast.
- Creativity
Creative design makes your product stand out on the shelf and grabs attention.
It builds your brand personality without losing clarity.
Real-world examples:
Use unique, high-impact patterns or shapes that match your brand style.
- Consistency
A matching visual style across your packaging builds recognition, trust, and long-term memory.
This works across all products and sales channels.
- Consumer-Centricity
Every design choice puts the customer first:
their needs, ease of use, lifestyle, and emotion.
It builds your brand personality without losing clarity.
Real-world examples:
Adopt sustainable and eco-friendly materials to match consumer values.

Step 2: How to explain your design needs clearly?
Most people skip this step.
But a clear brief will save you hours of miscommunication.
It stops the final design from feeling nothing like you imagined.
You don’t need to overthink about this part.
Follow these steps to make a professional design brief:
a) Start With Your Product and Brand
Great packaging design always starts with clarity about the product.
Before contacting a designer, prepare the following:
- Your product’s main advantages
- Specific customer usage scenarios
- Your target customer avatar
- Your target market and sales channels
- What matters most to your brand (your core values)
Do not say:
“We sell premium dog food and want a nice design.”
Instead say:
“We sell gluten-free salmon dog food for small indoor dogs aged 1–5.
Our customers are urban pet owners who treat their dogs like family.
We sell mainly through ecommerce and boutique pet stores.
Our brand stands for transparency, health, and emotional bonding.”
See the difference?
In the second example, your designer can immediately visualize the customer.
They can prioritize the right messages on the packaging.
Specific inputs create focused design outputs.
b) Share designs you love, and why
Do not just say, “I like this design. It’s good looking”
Explain why.
For example, describe the style, fonts, layout, or your favorite spot embellishments.
This will help the designer understand your preferences more accurately.
You can collect inspiration from platforms like Packaging of the World, The Dieline, and Behance.
Packaging of the world
The Dieline
Behance
Then write down:
- What catches your eye.
- The design’s biggest strength.
- Changes you would make.
For example:
“I like this layout because the product benefit is visible in the top third of the bag.”
“I like how the color palette feels clean and clinical.”
“I would simplify the typography.”
This gives your designer direction, not confusion.
c) Know your deadline
This is critical.
Your design timeline affects production, pre-launch, and your product launch.
Pro tip:
Your competitor is always the best teacher
Remember this:
The goal of packaging design is not decoration.
It is sales.
If a product is already selling extremely well, its packaging is proven effective.
You can search your product category on Amazon, Walmart, or other major retail platforms.
Identify top-selling products and study their design.
This gives your designer proven commercial direction instead of pure guesswork.
Design driven by market validation is rarely wrong.
Step 3: Where to Find Your Designer?
a) Ask Your Network
As an entrepreneur, you can get recommended designers through your contacts, industry groups, forums, and business communities.
Ask who they’ve worked with.
Referrals build trust fast.
Best of all: you get honest, real feedback.
b) Use Social Media
My top pick: LinkedIn.
It’s full of working professionals and expert designers.
Where you can make lowest effort to find qualified talent.
Second: Instagram.
It’s highly visual, perfect for finding packaging designers and know about them.
Search hashtags like:
#packagingdesigner
#flexiblepackagingdesign
#productpackagingideas
c) Use Freelance Platforms
You do not need to explore every platform.
Most operate similarly.
Here are four top options:
Design-focused community. High-quality portfolios. Often more premium pricing.
Contest-based model. Multiple designers submit concepts. Good variety, but quality varies.
Wide talent pool. Flexible pricing. Requires more screening effort.
Budget-friendly options. Fast turnaround. Quality ranges from excellent to very basic.
Keep in mind:The platform does not guarantee quality.
Your screening process does.
d) Ask Your Packaging Supplier
Many packaging suppliers have their own designers and industry connections.
This is a great choice for simple needs: logos, text, layout, or size changes.
Important Note
Always confirm that your designer delivers the final files in Adobe Illustrator vector format or PDF/X-1a.
Vector files are easy to edit and essential for high-quality printing.
Step 4: Ways to Choose Your Perfect Designer
Now you know what good design looks like.
And you have several designers to consider.
Before you make a final decision, you need to confirm whether the designer truly meets your requirements.
a) Check their portfolio
Every great designer proudly shows their best work.
Use their portfolio to see if their style fits you.
You can even research the real‑world sales of the products in their portfolio.
This shows you if their designs actually help products sell.
b) Ask About Industry Experience
If you like their work, ask if they’ve designed packaging for your niche.
Experience cuts down miscommunication.
c) Clarify Budget and Revisions
Is their pricing within your budget?
Do they offer free revisions?
How many revision rounds are included?
Clear pricing structure and defined revision limits protect you from cost overruns.
Ambiguity here often creates conflict later.
d) Test Whether They Truly Listen
This is make-or-break.
Even a designer with amazing work will fail you if they don’t care about your brand.
Here’s a simple test:
I call it Attention Check Method.
Add a small, harmless request to your brief that has almost nothing to do with the design.
Example:
“Please start your reply with the word “PackagingReady”
When they reply, you’ll know instantly if they paid attention.
3. How to Design It Yourself as a Beginner？
Don’t need complex packaging design,or short on time or budget?
No problem.
Many wholesalers and distributors face this exact situation.
a) Packagingseller
PackagingSeller provides ready-to-edit packaging designs.
These templates are as close to finished designs as you can get.
You only need to change your logo and text to use them.
Pros:
- Beginner-friendly
- Low cost: $2.39 for templates, $17.99 for exclusive designs
- Delivers files in multiple formats (including Illustrator) for easy editing
- Offers paid template modification services
Cons:
- Limited number of design templates
- No custom size selection
b) Canva
Canva is one of the most popular online design tools, and it works for packaging too.
Pros:
- Extremely beginner-friendly
- Huge library of elements and templates
Cons:
- Does not support vector graphics, which may lower print clarity
- Canva Pro is required for packaging design
Important Note:
If you use Canva:
- Export as PDF Print
- Select CMYK color profile
- Do not enable crop marks or bleed
- Canva Pro is necessary for proper export options
c) Kittl
Kittl is another rising design platform.
Compared to Canva, it offers:
- More advanced typography control
- True vector-based editing
- More professional text effects
- Strong branding-style templates
This makes it more suitable for packaging than Canva in many cases.
However:
- Template quantity is smaller than Canva
- Slightly steeper learning curve
If your design relies heavily on typography, badges, or structured layout, Kittl often performs better.
Canva vs. Kittl: Which Should You Choose?
Choose Canva if:
- You want maximum simplicity
- You prioritize speed
- Your design is minimal
Choose Kittl if:
- You care about typography quality
- You want stronger vector control
- You want something that looks more custom and less template-based
Neither replaces a professional designer.
But both can produce workable results for simple projects.
About AI Tools
The Pouching team has tested every major AI design tool under the sun.
Here’s our clear conclusion:
Right now, AI cannot replace human designers for production-ready packaging.

Legal Note
When using any of these tools, stay safe from copyright infringement.
This applies to fonts, graphics, and all stock assets.
Always carefully read and follow the usage policies of every element you use.
4. How to Check If Your File Is Print-Ready？
By now, you have completed your packaging design.
Before moving into production, there is one critical step:
Make sure your file is truly print-ready.
This step is essential.
Mistakes here will directly ruin your printed result.
I’ll give you a full print‑ready artwork specifications, covering:
a) Color Specifications
Incorrect color setup is one of the most common printing issues.
Always Use CMYK (Very Important)
Printing uses the CMYK color model, not RGB.
If you are using Canva:
- Export as: PDF Print
- Select color profile: CMYK
- Do NOT check: Crop marks and bleed
Flatten PDF
Include notes
Submitting an RGB file may result in noticeable color differences.
PMS Colors (Pantone)
If you are trying to match a Pantone® color:
- Refer to the Pantone Bridging Swatchbook
- Choose a color from the CMYK column
Please note:
A normal printing tolerance of 5%–10% color variation is industry standard.
Black Color Setting
Use: 100% Black (K100)
Avoid using rich black or heavy black mixes, as they can cause CMYK printing alignment problems or ink saturation issues.
b) Template Guide
Avoid Placing Critical Information in Heat Seal & Zipper Areas
Yes, these areas can be printed.
But never print critical info here. It will hurt user experience and compliance.
Important information includes:
- Barcodes and QR codes
- Nutritional facts panels
- Ingredient lists
- Allergen information
- Compliance warning statements
- Manufacturing and expiration dates
- Batch or lot numbers
Common compliance icons in US and EU markets include:
- USDA Organic
- FDA Compliance
- CE Mark
- UKCA Mark
- EPA Logo
- Recycling symbols
- FSC Certification
Here is the reason:
Heat seal areas are exposed to pressure and temperature.
Zipper areas may wrinkle.
Both can affect readability and scannability.
BORDERS
If your artwork has borders.
It’s thickness should be at least3/8″ (9.5mm) from the trim line in order to preserve the symmetry of your design.
Use Vector Graphics Whenever Possible
All non-photographic elements should be created in vector format:
- Text
- Lines
- Icons
- Illustrations
Vector graphics ensure sharp and clean printing results.
Confirm Bag Features, Finishes & Touch Effects
Your bag design schematic shows the final product 1:1.
It includes all features: zippers, tear notches, hang holes, valves, spouts.
It also shows the finish (gloss, matte, metallized, foil stamping) and feel (like soft-touch matte).
If something isn’t on the schematic, it won’t be on your final bag.
Always double-check every detail.
Spelling & Grammar
Once it’s printed, you can’t change it.
Take 2 minutes to proofread, it saves you from costly mistakes.
Test Barcodes & QR Codes
Before printing, scan the barcodes/QR codes on your design.
Make sure they’re scannable and lead to the right place.
Bar-code Specifications:
- Size: Recommended scale between 80%–120%.
- Do not crop or truncate the barcode.
- Format: Must be provided as vector line art.
- PNG images alone are not acceptable.
QR Codes Specifications:
- Recommended size: 20 × 20 mm
- Recommended color scheme: black code on white background (highest contrast)
Print-Ready Sample File
Below is an example of a print-ready file for reference:
c) File Formatting Checklist
Final File Type
Please submit a high‑resolution PDF (PDF/X‑1a:2001).
You can also provide your original AI source file.
Convert All Text to Outlines
First, save a backup file.
This step cannot be reversed.
In Adobe Illustrator:
Select > Object > All Text Objects > Type > Create Outlines.
Embed All Images
Unembedded images may be missing when the file is opened.
In Adobe Illustrator:
WINDOW → LINKS → Select the image → Choose “Embed Image(s)”
File Resolution
For the best print quality, set all images to 300 PPI.
Remove Printer Marks & Unused Layers
Remove all printer marks: crop marks, die lines, color bars, registration marks.
Delete or turn off all unused layers.
This keeps your file small and easy to process.
Clear Areas Definition
Clear areas need to be clearly defined and include a white separation.
White separation is a dedicated white ink layer used when printing on transparent or metallic materials.
It prevents transparency or metallic show-through and helps colors appear solid.
Bleed
In most cases, you do not need to create bleed manually, as your manufacturer will set it up during production.
If you do create bleed:
Use a minimum of 1/8 in (3 mm) on all sides.

How to Find and Work with the Right Packaging Supplier
There are hundreds (if not thousands) of packaging suppliers you can find in no time.
But you’re still stuck scrolling, comparing, and guessing which one can truly deliver for you？
Don’t worry.
In this chapter,
I’ll show you how to find and select the best supplier that truly deliver.
Step by step.
1. Prepare a Complete Request List
Before you talk to any supplier, you need a full request list.
It will cut down your communication time.
It will also rule out suppliers who don’t have the right production skills.
Your complete request list should include these details:
a). Order Quantity
List how many pouches you need for each design.
This directly determines your printing method: rotogravure or digital.
In most cases, suppliers specialize in only one printing method.
If you’re not sure which one is right for you, review this guide:
Rotogravure vs. Digital Printing – What’s the Difference?
b). Bag Type & Size
Specify your pouch type and dimensions.
For example:
Stand-up pouch, 130mm × 220mm + 60mm bottom gusset
Common pouch types include:
Stand-up pouch
Flat pouch
Spout pouch
Side gusset / Quad seal pouch
If you’re unsure, you can share a reference image.
c). Product Type & Capacity
Let your supplier know what product will go inside the pouch.
For example:
Powder (protein, supplements)
Liquid (juice, sauce)
Solid (snacks, coffee beans)
Also include the capacity:
100g / 250g / 500ml
This helps determine the correct size, material, and thickness.
d). Special Features
List any functional requirements for your pouch:
- Zipper
- Tear notch
- Hang hole
- Spout
- Degassing valve (for coffee)
- Window
These features will affect both cost and production complexity.
e). Shipping & Delivery
Provide basic logistics information:
- Destination country
- Preferred shipping method (air / sea)
- Required lead time (if any)
This helps suppliers give a more accurate total cost and timeline.
f) Packaging Design File
A design file (artwork) is required for an accurate quotation.
This allows the supplier to fully understand your specifications and provide precise pricing.
For rotogravure printing, the artwork is also required to calculate the plate (cylinder) cost.
If you don’t have a design yet, most suppliers can assist with dielines and setup.
g). Packaging Structure (Optional)
Your supplier can recommend this for you.
However, if you have ordered custom packaging before and know its laminate structure, you may provide it.
This will ensure that your new pouch maintains the same feel as your old one.
h). Packaging samples (optional)
If you have samples from previous orders, you can share them for reference.
This helps suppliers better understand your expectations in terms of:
- Material
- Thickness
- Finish
- Overall quality
2. Twelve Must-Ask Questions When Choosing a Packaging Supplier
Choosing a supplier is not just about price.
It is about long-term reliability, technical capability, and risk control.
Below are the key questions you must evaluate carefully.
1. Is communication fast and professional?
This is critical.
Only suppliers who reply quickly and give expert answers will take your order seriously.
It also proves they have the expertise you need.
2. Do They Have Experience in Your Industry?
Ask them to show you similar packaging projects.
Experience means they understand your needs.
They can also share expert tips on packaging trends, materials, and techniques.
3. Do They provide Samples?
Sample pouches are the best way to check if your final product meets your expectations, especially before mass production.
This can save you a lot of time and costly mistakes.
In flexible packaging, multiple sample options may be available:
- Similar standard pouches (to evaluate the supplier’s overall quality and workmanship)
- Unlaminated printed film (to check print quality)
- Laminated film (to confirm final color)
- Finished pouches (to check overall quality and look)
4. Have You Verified Real Customer Reviews?
Fake reviews are everywhere online, especially with AI‑generated content.
You need smart ways to spot genuine feedback.
Here are 2 effective methods for you:
a):
Check their website reviews, testimonials, and case studies.
Find the brands they show, and reach out to hear their real experience.
Brands used in case studies are often willing to share their real cooperation experience.
b):
Check B2B platforms, social media, and Trustpilot(if available).
Real customers share honest experiences here.
Cross-check across multiple channels, and you’ll clearly see their strengths and weaknesses.
5. Do they offer design support?
A reliable packaging supplier has in‑house designers.
They can fix small design issues or even create a design for you.
Design support proves their experience and saves you time.
6. Do They Support Factory Audits?
Audits help you avoid traders or factories that lie about their size.
You can choose:
- Video audit (via live video call with the supplier’s representative )
- In‑person audit
- Third‑party audit (TÜV, SGS, BV) if you can’t visit.
If a supplier says no to audits, be careful.
Make sure their reason is honest and reasonable.
7. Do They Hold the Necessary Certifications?
Find out which certifications are required for packaging in your target market,
and confirm with your supplier that they can meet your requirements.
8. Is there a setup / start fee?
Custom packaging needs machine setup and molds.
This creates fixed costs.
Some suppliers hide this fee to make the unit price look lower.
Always confirm your quote is the final price.
Avoid hidden costs that break your budget.
9. What Is the Lead Time?
Make sure the lead time fits your schedule.
Late delivery can mess up your launch and marketing plans.
10. What Delivery Terms Do They Offer?
For startups, DDP (Door to Door, Duty Paid) is the most convenient.
Common shipping terms:
- DDP: Door to door, all duties paid
- FOB: Buyer arranges international shipping
- CIF: Seller covers cost, insurance, freight to port
- EXW: Buyer handles all shipping from the factory
11. Do They Offer Color Matching Service?
Color matching means adjusting during production to stay close to your target color.
Color consistency is key for brand recognition and a premium look.
12. What Is the Lifespan of the Printing Plates?
For rotogravure printing, many buyers forget about plate storage and re‑use policy.
Ask these questions:
- Will they store your plates for you? (This should normally be free of charge.)
- How long will they keep them? (Typically 5–10 years.)
- How many runs can each plate handle? (Normally good for millions of meters of film.)
- Will you be charged again for re‑use? (This should normally be free.)
At Pouching, we provide free plate management and lifetime storage solutions to help you control reprint costs and maintain consistent quality across every production run.

How to Improve Existing Packaging Without Starting Over
Great!
You’ve now mastered the entire process of flexible packaging customization from start to finish.
There’s one key point you should also plan for:
What costs will you incur if you need to adjust your packaging later on?
And how can you avoid unnecessary expenses?
In this chapter,
I’ll break down packaging modifications into 2 levels and explain the actual costs for each.
So without further ado, let’s get started.
Level 1: Visual Change or material change
This means you only update the artwork or layer material of your pouch, while keeping the same shape and size.
For digital printing:
No plates are needed at all, so changing the design adds zero extra cost.
For rotogravure printing:
A new design requires new printing plates, so you will need to pay a plate fee.
Level 1 works best when:
You have multiple product styles, models, or flavors that need different designs.
Note:
If your new design uses special effects like spot gloss or foil stamping, you may pay extra for these processes.
For material changes, only material cost changes apply, no plate fee.
Level 2: Size & Shape Change
For digital printing:
Small changes in size and shape do not create new design costs, if your original design can be scaled up or down to fit the new size.
But changes in size and shape will affect material and processing costs, this applies to both printing methods.
For rotogravure printing:
Changing size and shape also changes the design.
You still need new plates to fit the new dimensions, which results in a new plate fee.
Level 2 works best when:
Your products come in different weights or volumes and require different pouch sizes.
7 Simple Ways to Test Your Pouches Before Use
If you’ve already received your pouches,
how can you quickly check if they’re ready to use?
Here are simple steps you can use:
- Pull the seal by hand to test if it’s strong.
- Smell the pouch for any strange odors.
- For bottom gusseted pouch like stand up pouches, place it on a table to check stability.
- Open and close the zipper repeatedly to test durability.
- Rub the printed area to check if ink stays firmly.
- Compare multiple pouches to check color and size consistency.
- Fill the pouch with air, seal it tightly, submerge it in water, and gently squeeze to check for leaks or poor sealing.
Conclusion
That’s the complete guide to flexible packaging customization.
Learning all these steps does take a little extra work.
But once you master these key points, you can better communicate with suppliers, avoid costly errors, and ensure your products stand out on retail shelves.
