Key Parameters
Key parameters of CPP and composite membrane
The CPP composite structure takes the heat-sealing inner layer and composite fastness as the core, which must be confirmed in combination with bag type, packaging speed, temperature resistance and content.
| structural level | PET/BOPP/PA outer layer + composite adhesive layer + CPP heat-sealed inner layer, or VMCPP/VMOPP metallized structure | First distinguish the directions of outer printing, barrier layer and inner layer heat sealing. |
|---|---|---|
| Key Parameters | Sealing temperature, heat sealing strength, COF, puncture resistance, composite fastness, temperature resistance | Cooking, freezing and high-speed packaging must be verified at actual packaging machine speeds. |
| application boundaries | Retort bags, frozen food, facial tissue packaging, anti-fog packaging, high-slip packaging | Anti-fog and steaming products cannot directly apply ordinary CPP parameters. |
| Information confirmation | TDS, Batch Reporting, Food Contact, Compound Fastness, Heat Seal Samples and Bag Samples | Formal orders confirm information by structure and batch. |
