3. Tape casting polypropylene CPP: good luster, good transparency, heat sealing, tape casting high temperature film is suitable for cooking and packaging
4. Polyethylene PE: transparent, good gloss, heat sealing, cold resistance
5. Polyester film PET: with tension resistance, heat resistance 60-150 degrees, good air tightness, suitable for cooking, no heat sealing
6. Nylon PA or NY: colorless, high transparency, cold resistant, heat resistant, oil resistant, can be cooked. Easy to absorb moisture, no heat sealing
