Technical Parameters
Key Specifications
| Thickness range | The common CPP cast film is 18-200μ, and the inner layer of general packaging is usually 20-60μ. |
|---|---|
| Heat sealing temperature | The sealing temperature of ordinary heat sealing CPP is about 100-120℃, confirmed by the grade and layer ratio |
| heat-seal strength | CPP for packaging often uses ≥2.3 kg/in grade as a reference for similar products, and is officially tested according to N/15mm |
| COF | Ordinary/smooth grade COF is usually prepared in the range of 0.2-0.5, subject to the speed of the packaging machine. |
| Optical indicators | Transparent CPP focuses on haze, transmittance, crystal point and thickness uniformity |
| surface tension | Recommended for printed or composite surfaces ≥38 mN/m, corona attenuation needs to be retested |
| source boundary | This table is a combination of public parameters in the CPP industry. The official indicators are based on the casting line formula and batch TDS. |
