Silicone Coated Polypropylene Release Film,light weight, high transparency, good flatness, good rigidity.
| Characteristics | CPP film is a non-stretching, non-oriented flat extrusion film, with light weight, high transparency, good flatness, good rigidity, strong mechanical adaptability, excellent heat sealability, moisture resistance and heat resistance, and smoothness. Good performance, high film-making speed, uniform thickness, moisture-proof, oil-resistant, heat-resistant and cold-resistant, easy to heat seal, and its anti-squeeze and packaging machinery applicability are better than polyethylene film and so on. It has excellent optical properties and can be used for automatic packaging. CPP film can be used in the packaging of food, medicine, stationery, cosmetics and textiles through bag making, and it is the largest in food packaging. CPP film is used to package heat-sterilized food, condiments, soups, etc.; it can also be used for the surface layer, interlayer and auxiliary film of stationery products, such as loose-leaf, protective film for photos and collections, and can also be used as various labels and sample tapes. In recent years, it has also been used in the field of lithium batteries |
