Technical Parameters
Key Specifications
| Reference structure | PET 12μ / CPP 50-80μ common, temperature resistant or heavy packaging, thickened according to CPP thickness |
|---|---|
| peel strength | Dry compounding/solvent-free compounding usually requires verification at the ≥1.0-2.0 N/15mm level |
| heat-seal strength | The heat sealing strength of the inner layer of CPP is confirmed based on the weight of the content, and ≥20 N/15mm is often used as a packaging reference. |
| heat resistant windows | PET provides dimensional stability, and CPP provides heat sealing; for 121°C cooking, you need to choose a cooking-resistant CPP. |
| blocking indicator | Ordinary PET/CPP barrier is mainly moisture-proof and oil-resistant. High barrier requires an aluminum plating or coating layer. |
| Application Scope | Condiment bags, daily chemical refills, heat-resistant food bags and industrial bags |
| source boundary | This table is a structural reference for PET/CPP counterparts. The official indicators are confirmed based on film thickness, glue and aging conditions. |
