Technical Parameters

Key Specifications

Reference structureBOPA 15μ / CPP 60-80μ common, frozen or heavy packaging adjusted according to inner layer thickness
puncture resistantBOPA provides puncture resistance and flexibility, and puncture/drop testing is required for sharp contents.
peel strengthAfter dry compounding or solvent-free compounding, it is recommended to verify according to the ≥1.0-2.0 N/15mm level.
heat-seal strengthThe heat sealing strength of the inner layer of CPP is confirmed according to vacuum, freezing or cooking scenarios, and is often referred to as ≥20 N/15mm.
Low temperature resistanceFrozen food bags need to be verified for flexibility and bag breakage under -18°C conditions
blocking indicatorBOPA's oxygen barrier is better than ordinary CPP, but it is affected by humidity. High barrier requires composite coating/aluminized layer
source boundaryThis table is a structural reference for BOPA/CPP counterparts. The official indicators are confirmed by nylon grade, moisture content and compounding process.
