Retort pouch material structure guide for high temperature sterilization.
Retort pouches need specific material structures to withstand high temperature sterilization.
Common structures: PET/AL/NY/CPP for maximum protection, PET/NY/CPP for non-foil, PET/AL/CPP for standard retort.
Pouch breaking during sterilization, seal leakage after retort, delamination between layers.
1. Confirm sterilization profile. 2. Select retort-grade materials. 3. Test with customer process. 4. Confirm sealing after retort.
Material confirmation, sealing strength, lamination strength, leakage test and sample testing.
Product type, sterilization temperature, pouch size, filling weight, quantity and artwork.
Designed for 121-135 degrees Celsius.
No. Retort requires specific grade materials.
Yes, before bulk production.
Use retort-grade adhesives and confirmed process.
