Product Applications

Choose Mylar Bags Around the Product Being Packed

Start with the product rather than the pouch appearance. Contents, filling method, storage conditions and how customers use the pack all influence the format and features worth specifying.

Mylar bags for coffee and tea products
01

Coffee & Tea

Consider aroma retention, reliable sealing and degassing-valve requirements where appropriate to the packed coffee product.

Mylar bags for snacks and confectionery
02

Snacks & Confectionery

Moisture management, resealability and shelf presentation are useful considerations for products consumed across more than one occasion.

Mylar bags for powders and supplements
03

Powders & Supplements

Prioritise dependable seal areas, practical filling and enough printable space for product information and variant identification.

Resealable Mylar bags for pet treats and dry foods
04

Pet Treats & Dry Foods

Resealable closures and practical larger pouch formats can support products repeatedly opened between servings.

Printed Mylar bags for cosmetics and personal care
05

Cosmetics & Personal Care

Presentation, potential leakage and compatibility between the packed product and pouch construction should be considered together.

Small printed Mylar bags for retail sample products
06

Retail & Sample Products

Smaller pouch formats can combine compact branded presentation with retail features such as hang holes where the chosen construction supports them.

Starting Point Product first. Pouch specification second.

Two products of a similar weight may still need different pouch specifications because their sensitivity, filling process, storage conditions and customer use can differ. The next step is to match the film construction to the barrier performance the product actually requires.

Barrier Performance

Match the Film Structure to the Barrier You Need

“Mylar” is commonly used as a market term for flexible barrier pouches, but pouch performance depends on the complete film or laminate structure rather than the name alone.

Material Clarification
Mylar® refers to PET film
The pouch specification is the complete construction.

Barrier performance can depend on the combination of film layers, coatings or metallisation, overall gauge and the heat-seal layer used in the finished pouch.

Barrier Requirement What needs controlling?
Why It Matters Typical product consideration
Specification Direction What to assess in the pouch build
01

Moisture Barrier

Moisture transfer

Relevant to dry foods, powders and products where moisture exposure or loss can affect the packed product.

Moisture-resistant film structure

Select an appropriate construction for the required moisture-barrier performance.

02

Oxygen Barrier

Oxygen exposure

Important to consider for aroma- or flavour-sensitive products where oxygen exposure needs greater control.

Higher-barrier laminate where required

Match the barrier construction to the product and its intended storage conditions.

03

Light Protection

Light exposure

Relevant where the packed product is sensitive to light or where an opaque pack is part of the specification.

Opaque or metallised construction

Consider a light-blocking structure where the application requires it.

04

Aroma Control

Aroma transfer

A consideration for coffee, tea and fragranced products where aroma retention is important to the pack brief.

Seal + suitable barrier structure

Review both the film construction and finished seal rather than treating aroma control as a film-only decision.

05

Puncture Resistance

Physical stress

Dense, irregular or sharper contents can place more mechanical stress on the pouch during filling and handling.

Film gauge + laminate strength

Assess the complete film build against packed weight, product shape and expected handling.

06

Seal Performance

Closure integrity

Filled retail packs need a seal specification compatible with the pouch construction and practical filling process.

Heat-seal layer matched to filling

Consider the seal layer, sealing method and production conditions as part of the final specification.

Specification Principle Don't specify the pouch by material name alone.

Start with what the packed product needs to resist, then select the film or laminate construction accordingly. Barrier level, film strength and seal performance should be considered as parts of the same pouch specification.

Size & Format

Specify the Bag Size and Film Build Around the Product

Pouch size should be based on the filled product, not an empty bag alone. Product volume, weight, filling method, headspace and handling all influence the finished dimensions and film build.

Dimension Reference How are pouch dimensions measured?
Finished Dimensions

Width × Height × Gusset Where Applicable

Width and height define the main pouch dimensions. Stand-up and other gusseted formats also need the gusset dimension considered because it contributes to usable capacity when the pouch is filled.

Measure the finished pack Check dimensions against the actual product volume and intended fill level before approving the pouch size.
01 Size Decision

Finished Dimensions

Specify width, height and gusset where applicable around the required filled pouch rather than selecting dimensions from the product weight alone.

Width × Height × Gusset
02 Capacity Decision

Filled Volume & Weight

Design around the real filled pack. Products with the same weight can occupy different volumes, so weight alone does not determine the correct pouch dimensions.

Product + Fill Level + Packed Weight
03 Film Decision

Film Thickness

Film build should follow packed weight, puncture risk and expected handling. A thicker film is not automatically the better specification for every product.

Weight + Contents + Handling
04 Filling Decision

Seal Area & Headspace

Leave enough unfilled area for practical filling and reliable sealing without unnecessarily increasing the overall pouch dimensions.

Fill Line + Headspace + Seal Area
Pack Format

Stand-Up or Flat Pouch?

The appropriate format depends on how the product is filled, presented and used rather than appearance alone.

Stand-Up Pouch

A gusseted base adds usable capacity and allows the filled pouch to stand for shelf presentation where suitable.

Flat Pouch

Useful where a compact profile, smaller fill or space-efficient pack is more important than a freestanding base.

Does a powder need the same pouch build as coffee?

Not necessarily. Different products can create different requirements for filled volume, barrier performance, seal behaviour and handling, even when the nominal pack weight is similar.

What changes for larger packs?

As filled weight and pouch dimensions increase, film strength, seal area, gusset design and handling conditions become more important parts of the specification.

Specification Note

A universal film thickness should not be assumed. The appropriate build should be selected from the actual packed product, required barrier performance, pouch size, filling process and expected handling conditions.

Closures & Features

Add Features That Match How Customers Use the Pack

Functional features should solve a specific packing, opening, storage or display requirement. Select them around how the pouch will be filled, sold and used rather than adding every available option to the specification.

Repeat-Use Feature

Resealable Zipper

Useful for products that customers open and close repeatedly between uses.

Opening Feature

Tear Notch

Provides a defined starting point for the customer's first opening of a suitable sealed pouch.

Display Feature

Hang Hole

Supports peg or hanging retail presentation where the pouch format and packed weight are suitable.

Coffee Application

Degassing Valve

Relevant to coffee applications where the product specification calls for controlled gas release.

Format Feature

Gusset / Stand-Up Base

Adds usable filled capacity and can provide a stable standing format for suitable shelf applications.

Closure Feature

Heat-Seal Area

Provides space for an initial sealed closure and can support tamper-evident presentation where appropriate.

Visibility Feature

Window

Allows product visibility where a window is compatible with the selected pouch construction and the barrier requirements of the packed product.

Check Before Specifying Visibility can change the overall barrier specification.
Feature Compatibility Not every feature suits every pouch construction.

Availability should be confirmed against the selected film structure, pouch format, packed product and filling requirements. A zipper, valve, window or other feature should not be assumed to be compatible with every material build.

Print & Presentation

Print Mylar Bags for Clear Retail Branding

Printed pouch artwork needs to do more than carry a logo. Plan colour, product information, surface appearance and SKU differences together so the range remains recognisable while each product is easy to identify.

Custom printed Mylar bags with branded retail artwork
Retail Presentation One brand system, clear product variants
01
Colour

Brand Colour

Use full-colour artwork and define important brand colours clearly so packaging across the range follows a consistent visual system.

02
Information

Product Information

Reserve suitable artwork areas for ingredients, instructions, product variants, batch details and barcodes where applicable.

03
Presentation

Surface Appearance

Matt, gloss, metallic and other supported presentations can change the visual character of the finished pouch and should be considered with the artwork.

04

Food Contact & Compatibility

Confirm Food-Contact Suitability for the Intended Use

For food applications, the complete pouch structure, inks, adhesives and other relevant components should be suitable for the intended food-contact conditions. Requirements can vary by product, temperature, duration of contact and construction.

Specification Principle

“Food-safe” should not be treated as a blanket pouch claim.

Suitability needs to relate to the actual packaging specification and the conditions in which the packed product will contact or interact with it.

Product + Contact + Conditions + Pack Build
01 Contact Condition

Direct or Indirect Contact

Establish whether the product will directly contact the pouch interior or whether another primary pack or layer sits between the food and the pouch.

Define the actual contact arrangement.
02 Packed Product

Food Type

Dry, fatty, acidic and other food types can create different compatibility considerations, so the intended contents should form part of the material brief.

Specify what will be packed.
03 Conditions of Use

Temperature & Storage

Consider expected filling, storage and use conditions, including temperature and how long the product is expected to remain in contact with the packaging.

Define realistic use conditions.
04 Verification

Required Supplier Documentation

Confirm the documentation relevant to the proposed materials and intended application before relying on food-contact or compliance claims.

Verify the selected specification.
Great Britain Regulatory Context

Check the Actual Food-Contact Specification

The Food Standards Agency maintains the official register for authorised plastic food-contact substances in Great Britain, including applicable restrictions and specifications. Suitability should therefore be established for the materials and intended conditions of use rather than inferred from the term “Mylar” alone.

FSA Food-Contact Register
Before Approval

Tell the packaging supplier what the pouch will contain and how it will be used. Product type, direct-contact requirements, filling conditions, storage temperature and expected contact duration can all affect the suitability assessment.

Material & Supply Planning

Plan Material Use and Repeat Supply Together

A practical pouch specification should consider both material use and future ordering. That means avoiding unnecessary material while keeping approved dimensions, film construction and artwork references clear for repeat production.

01
Sustainability Consideration

Material Efficiency

Reduce material where the pouch can still meet its required filling, barrier and handling specification.

Right-Size the Pouch

Match dimensions to the real filled product rather than carrying unnecessary pouch area.

Avoid Unnecessary Film Thickness

Specify film around the packed weight, contents and handling requirements rather than assuming thicker is always better.

Review Every Component

Zippers, valves, windows and other components should have a clear functional reason for being included.

Assess Recyclability Carefully

Review mono-material or recyclable structures where available and suitable, and verify the relevant recycling route before making disposal claims.

Claim Carefully

The complete pouch construction matters. Film layers, closures, valves, windows, inks and other components can affect the recyclability of the finished pack.

Frequently Asked Questions

In packaging, the term Mylar bag is commonly used for flexible barrier pouches that include PET or polyester film, often combined with other layers such as polyethylene or metallised film. The exact construction depends on the required moisture, oxygen, light and puncture resistance. Different products may therefore need different laminate or film structures rather than one standard material.
