Frozen Food
Flexible Packaging for Frozen Food
Frozen packaging fails in ways dry-snack bags usually do not. Seals see frost and product in the seal area. Corners crack in the cold. Sharp pieces puncture the film. The bag then has to stay intact through a long cold chain.
Walter Solutions helps Canadian brands specify flexible packaging for frozen foods. Where a polyethylene-based structure meets the seal and toughness requirements, it can be designed for PE recycling streams. Frozen performance is confirmed in trials. It is not assumed because a film is mono-material.
Products we pack
- Frozen vegetables and fruit
- Frozen meat, poultry and seafood
- Frozen prepared meals and dumplings
- Frozen snacks and appetizers
- Ice-packed or tempered products that are sealed cold
- Private-label frozen lines
Formats
- Stand-up pouches
- Pillow and three-side-seal bags
- Rollstock for automated lines
- Easy-tear or tear-notch openings
- Zippers only when the product is meant to be reclosed and your line can seal them reliably
What we look at first
- Seal strength through frost, fat, marinade or product fragments
- Puncture and tear resistance at frozen temperatures
- Film toughness so the bag does not crack in distribution
- Barrier enough for the shelf life you need in frozen storage
- Format that runs on your filler: pre-made pouch or rollstock
- How the empty bag should be described once the consumer is finished with it
Structures
PE/PE is the option to test first when you want a structure designed for PE recycling streams. We only move forward if seal, puncture and cold-crack checks are acceptable for your product.
PP/PP Premium is the higher-cost option when heat, humidity or the product itself needs a more stable barrier. It is a performance choice, not a frozen-food default.
Deep-freeze conditions, bone-in meat, shells and hard vegetable pieces can disqualify a structure that works for a dry snack. Send the product you actually fill.
What we will not claim
A frozen bag is not “100% recyclable” because it is made mainly from PE. Food residue, inks, zippers and labels change both recycling and what a program will accept. Many Canadian curbside programs do not take flexible film at all.
Preferred on-pack language is “designed for recycling” or “recycle where facilities and programs exist.” The wording is reviewed with the finished bag and with the provinces where you sell. See our recyclability language.
What to send
- Current bag and the product type
- Fill temperature and whether the seal area gets wet or contaminated
- Target frozen shelf life
- Distribution: case size, stacking, retail freezer
- The claim you want on pack
We recommend a structure and samples. A line trial should include real product, not an empty-bag seal test only. You confirm shelf life.

Recyclability notice
Recycling acceptance and collection methods vary by province, municipality and recycling program. A package described as “designed for recycling” has been developed with material compatibility in mind but may not be accepted in every local collection system.
