Sinopec casting polypropylene (CPP) film materials are used in the surface and internal layers of CPP film. CPP films produced using these resins are characterized by high transparency, good stiffness, low heat sealing temperature, heat and moisture resistance, good barrier properties, available for printing and recombination adaptability, smooth surface, and good steam boiling resistance. The films produced by CPP are homogeneous in thickness and have highly balanced properties.
CPP is widely used in the production of inner heat-sealing films of laminated films, films for use in vacuum aluminum coating, films for use in high-temperature steam and boiling, packaging films, matt film, and metalized films. It is also widely used as the packing for clothing, stationery, food, medicine, cosmetics, textiles, etc.
