Compared with other film products, cast polypropylene film CPP film has the characteristics of good transparency, high gloss, good stiffness, good moisture resistance, excellent heat resistance and easy heat sealing. The film can be used in the fields of hot filling, retort pouch, aseptic packaging and the like. Plus acid, alkali and grease resistance, making it the material of choice for bread packaging or laminates.
In the actual application process, the CPP film is safe in contact with food, has excellent demonstration performance, does not affect the flavor of the built-in food, and can select different grades of resin to obtain the desired characteristics.
