Custom pouches can make your products look right at home on a retail shelf, keep them fresh through shipping and make everyday use easier for customers. But with so many pouch types, materials and thickness options, how do you know which combination will work best for what you’re selling?
From stand-up bags for snacks to high-barrier films for coffee, this guide breaks down the options, explains what the specifications actually mean and shows you how to choose and test the right packaging for your product and budget.
- The main pouch types include stand-up, flat, gusseted and spouted pouches, each suited to different products, capacities and display needs.
- Common pouch materials include PET, PE, EVOH and aluminum foil, often combined to provide strength, heat sealing and protection against oxygen, moisture and light.
- Pouch thickness is measured in mils, microns or gauge and affects flexibility and durability, although thicker films don’t necessarily offer better barrier protection.
- Functional pouch features such as resealable zippers, tear notches, hanging holes and degassing valves improve convenience, freshness and retail presentation.
- To choose the right custom pouch, consider your product’s protection needs, size, storage conditions and budget, then test samples before ordering.
Their main benefits include:
- Product protection: Help shield contents from moisture, oxygen, light and contamination.
- Lower shipping and storage costs: Weigh less and take up less space than many rigid packaging options.
- Brand visibility: Offer customizable printing, shapes and finishes.
- Convenience: Can include resealable zippers, tear notches and other easy-to-use features.
Of course, not every pouch offers the same benefits. Its shape, materials and construction determine what it can hold, how well it protects the contents and how customers use it.
Different pouch types and their best uses
Before choosing your packaging, it helps to separate pouch types from pouch materials. The type determines the pouch’s shape and how it holds your product, while the material determines how well it protects the contents. You can often get the same pouch style in several different films.
Stand-up pouches
Stand-up pouches have an expandable bottom fold, called a gusset, that allows them to stand upright when filled. They’re a popular choice for retail products like granola, dried fruit, pet treats, powders and cosmetics, thanks to their shelf stability and generous front-facing branding space.
The main consideration is stability – very small quantities or unevenly distributed contents can make these pouches tip over.
Add resealable zippers for products customers use repeatedly or hanging holes for peg displays.
VistaPrint offers stand-up pouches in white, clear and metalized films, with matte or gloss finishes.
Flat pouches
Flat pouches are sealed around the edges without an expandable base, making them particularly useful for samples, single servings, spices, powders and small accessories.
Their slim profile also makes them easy to pack into subscription boxes or shipping mailers. However, retail display options are more limited unless you add a hanging hole or use secondary packaging.
VistaPrint’s flat pouches come with the same film, finish and zipper options as its stand-up range.
Gusseted pouches: Side-gusset and flat-bottom
For bulkier products, gusseted pouches provide extra capacity through expandable panels.

Two common designs are:
- Side-gusset pouches: Expand along both sides to accommodate coffee beans, loose-leaf tea and larger quantities of dry goods. They may need support to stand upright.
- Flat-bottom pouches: Combine side gussets with a flat base for better shelf stability and additional branding space. Often used for premium coffee and specialty foods.
Both offer greater capacity than comparable flat pouches, but their more complex construction can increase production costs.
Spouted pouches
For liquids and pourable products, spouted pouches offer a practical alternative to bottles. They feature a built-in dispensing spout and reclosable cap, allowing customers to pour sauces, purees, liquid soaps or detergent refills with less mess.

They’re convenient for storage and dispensing, but require films compatible with the contents, reliable leak-resistant seals and suitable filling equipment.
Pouch types compared
| Pouch type | Best for | Main advantage | Main limitation | Typical retail advantage |
| Stand-up | Snacks, pet treats, powders | Stable upright design | Needs sufficient fill for stability | Prominent shelf-facing branding |
| Flat | Samples, spices, accessories | Compact, often economical | Cannot stand independently | Peg displays and small-format merchandising |
| Side-gusset | Coffee, tea, bulk dry goods | Expandable capacity | May need support to stand | Efficient packaging for larger quantities |
| Flat-bottom | Premium coffee, specialty foods | Stable base, multiple panels | More complex, often costlier | Premium shelf presentation |
| Spouted | Sauces, liquids, refills | Controlled dispensing | Specialized seals and filling | Convenient alternative to bottles |
Pouch materials explained: Layers, barriers and product protection
Most custom pouches combine several film layers, each responsible for strength, printability, product protection or heat sealing. Two identical-looking pouches can perform very differently depending on what’s inside.
Common pouch materials and their properties
Here’s what different pouch materials bring to the table:
| Material | Main properties | Typical role |
| PET (polyester) | Strong, stable, printable | Outer structural layer |
| PE (polyethylene) | Flexible, heat-sealable, moisture-resistant | Inner sealing layer |
| Aluminum foil | Excellent oxygen, moisture and light barrier | High-barrier layer |
| EVOH | Strong oxygen barrier, moisture-sensitive | Barrier layer |
| Kraft paper | Natural, textured appearance | Decorative outer layer with protective lining |
| Metallized film | Thin metal coating improves barriers and creates metallic effects | Barrier and visual effects |
There’s no universally best pouch material for food. The right choice depends on moisture and fat content, processing requirements and intended shelf life.

Understanding barrier properties and multilayer structures
Barrier pouch materials protect against three main threats:
- Oxygen: Causes oxidation, making nuts rancid and coffee lose flavor.
- Moisture: Softens crispy snacks and makes powders clump.
- Light: Degrades sensitive ingredients, including certain oils and vitamins.
Suppliers measure oxygen and moisture protection using OTR (oxygen transmission rate) and WVTR (water vapor transmission rate). Lower values generally mean stronger barriers under the same testing conditions.
Common film structures include:
- PET/PE: Strength and heat sealing.
- PET/EVOH/PE: Added oxygen protection.
- PET/AL/PE: High oxygen, moisture and light protection.
White, clear or metalized film: Which should you choose?
Beyond protection, pouch materials also influence how your packaging looks. Three common film options illustrate the difference:
| Film | Characteristics | Best for |
| White | Opaque, vibrant printing, EVOH barrier | Pet food, cosmetics, soaps |
| Clear | Transparent, EVOH barrier | Colorful products worth displaying |
| Metallized | Metallic appearance, enhanced barrier | Ground coffee, tea, herbs, spices |
All three are 4.8 mil thick and rated for direct food contact. Unlike aluminum foil, metalized film has a thin metal coating.
Mono-material vs. multilayer pouches: Which is more sustainable?
Mono-material pouches, such as mono-PE, are made mostly from one type of plastic, which can make them easier to recycle. Pouches made from several materials often offer better protection against oxygen and moisture, although some mono-material options can provide strong barriers too.

But whether a pouch can actually be recycled depends on how it’s made and what your local recycling facilities accept.

Pouch thickness guide: Mil, micron and gauge explained
Pouch thickness affects how flexible or stiff your packaging feels, how well it withstands handling and how much material it uses. Depending on the film structure, it can also influence puncture resistance. However, thicker doesn’t automatically mean better protection against oxygen or moisture.
What is the difference between mil, micron and gauge?
Pouch thickness is measured in three units:
- Mil: One-thousandth of an inch.
- Micron (µm): One-millionth of a meter.
- Gauge: A unit commonly used for plastic films, although conventions can vary between suppliers.
For quick pouch thickness mil to micron conversions, 1 mil = 25.4 microns, 1 micron ≈ 0.0394 mil and 100 gauge = 1 mil under the common plastic-film convention.
| Mil | Micron (µm) | Gauge |
| 2 | 50.8 | 200 |
| 3 | 76.2 | 300 |
| 4 | 101.6 | 400 |
| 4.8 | 121.9 | 480 |
| 5 | 127 | 500 |
| 6 | 152.4 | 600 |
For reference, VistaPrint’s custom pouches are 4.8 mil thick, equivalent to approximately 122 microns.
Functional pouch features: Closures, valves and finishes
The little details can make a big difference to how customers use your packaging. Closures help keep products fresh after opening, hanging holes determine how they’re displayed and finishes influence how your brand looks and feels.
Resealable zippers, tear notches and hanging holes
Consider how customers will open, store and use your product when choosing these features:
- Resealable zippers: Allow customers to close the pouch between uses, reducing exposure to air and moisture. Ideal for multi-serving snacks, coffee, pet treats and powders. VistaPrint’s optional single-track zipper sits 1.25–1.5 inches below the top, depending on pouch size.
- Tear notches: Allow customers to tear open heat-sealed pouches neatly without scissors. Especially useful for single-serving products and packaging designed for on-the-go consumption.
- Round hanging holes: Allow lightweight pouches to hang from standard retail hooks, freeing up shelf space. VistaPrint offers a 0.31-inch round hole.
- Euro hanging holes: Allow pouches to hang more securely on retail display pegs by distributing weight across a wider opening. VistaPrint’s option measures 0.39 × 0.98 inches.
- Heat seals: Allow pouches to remain securely closed until first use, helping prevent contamination and unwanted air or moisture exposure. Particularly important for food packaging, where seal integrity affects shelf life.
Degassing valves: Why coffee packaging needs them
Freshly roasted coffee releases carbon dioxide, which can make sealed pouches puff up. One-way degassing valves let the gas escape while keeping outside air out, helping preserve freshness alongside suitable barrier films. They’re especially useful for whole-bean coffee and work independently of resealable zippers.
Matte vs. gloss vs. soft-touch finishes
Your pouch’s finish affects its appearance, feel and shelf appeal:
- Gloss: Reflects light, making colors look vibrant and bold.
- Matte: Reduces glare for a softer, more understated appearance.
- Soft-touch: Adds a velvety feel, often associated with premium products, but can cost more and may require scuff testing.
Whichever you choose, make sure it complements your colors, graphics and overall product packaging design.

Consider these five factors before choosing a pouch
Once you’ve shortlisted a format, work through these questions before requesting a quote:
- Product characteristics: Is it dry, liquid, oily or sharp-edged? Could moisture, light or rough handling damage it?
- Protection and shelf life: How long must it stay fresh? Ask suppliers for barrier specifications that support your target shelf life.
- Size and capacity: How much product will it hold? Account for fill weight, volume, headspace and gusset expansion. External pouch dimensions aren’t the same as usable fill capacity.
- Sales and distribution: Will it stand on a shelf, hang from a peg or ship in a box? Consider how it will be handled along the way.
- Branding and budget: Which print quality and finish suit your brand? Compare minimum order quantities, unit prices and production lead times.
With those answers, you’ll have a much clearer specification to discuss with suppliers, rather than choosing packaging based on appearance alone.
How to test custom pouch samples before ordering
Specifications can tell you plenty about a pouch, but there’s no substitute for testing it with your actual product. A sample can reveal sizing issues, weak seals or printing problems before you commit to a bulk order.
Before testing, ask for:
- Samples in your intended size, format and film structure.
- Film thickness and, if relevant, OTR/WVTR barrier ratings.
- Seal compatibility and available closure options.
- Food-contact compliance documentation, if packaging food.
- Minimum order quantities, lead times and artwork requirements.
How to test pouch performance
Once your samples arrive, put them through these five checks:
- Fill test: Add your usual product quantity. Check capacity, headspace, stability and how easily the pouch fills.
- Seal test: Check heat-seal strength and whether zippers or other closures work reliably.
- Durability test: Simulate stacking, handling and shipping to spot punctures, crushing or leaks.
- Appearance test: Inspect printed colors, finish, readability and resistance to scratches or scuffs.
- Shelf-life test: For sensitive products, arrange appropriate testing to confirm freshness and barrier performance over time.
Happy with the results? Confirm the final dimensions, materials, closures and printing specifications with your supplier before placing the order.
Ready to create custom flexible packaging pouches?
Choosing the right pouch comes down to finding the best fit for your product, customers and budget. Now that you know how pouch types, materials and thickness affect packaging performance, you’re ready to make an informed choice. Just remember to test samples before committing to a bulk order.
Pouch types: FAQs
Are all custom pouches safe for food packaging?
No. Food packaging requires materials approved for contact with the intended food under its storage and processing conditions. Always request the supplier’s food-contact compliance documentation before ordering.
Can custom pouches be used for hot-filled products?
Yes, but only if they’re specifically designed for hot filling. Standard pouch films and seals may warp, weaken or leak at high temperatures, so confirm the maximum filling temperature with your supplier.
Do I need special equipment to seal custom pouches?
Most heat-sealable pouches require a compatible heat sealer to close them after filling. The equipment and settings depend on the film structure, pouch size and production volume.
How much do custom pouches cost?
Pricing depends on pouch size, materials, printing, closures and order quantity. Larger orders typically reduce the cost per pouch, but compare setup fees and minimum order quantities before committing.
