High Barrier Film for Frozen Distribution
Sep 23,2026 | FOSHAN CAILONG METALLIC PACKAGING MATERIAL CO.,LTD
High Barrier Film for frozen distribution must retain performance after the pouch becomes stiff, rubs against ice or product edges, and moves through handling. Flat-film data does not capture every cold-chain failure.
A Metallized Film Supplier needs the laminate, product shape, freezing temperature, storage time and transport method. Cailong publishes grade-specific data for VPET-GZ, while the finished frozen package requires separate qualification.
Reproduce the Cold Chain
Define filling temperature, freezing rate, storage temperature, carton loading and any thaw-refreeze exposure. Retain matched pouches for each stage.
Inspect Stress Locations
Check product corners, folds, seals and abrasion points for cracks, pinholes or delamination. Separate panel barrier loss from seal leakage.
Test after Handling
Measure package integrity and barrier after the distribution simulation, not only before freezing. Send Cailong the structure, cycle, failure map and samples.
