Sinopec casting polypropylene (CPP) film materials, are used in the surface and internal layers of CPP film. The films produced by CPP are homogeneous in thickness and have highly balanced properties.
Applications of the product
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 metallized films. It is also widely used as the packing for clothing, stationery, food, medicine, cosmetics, textiles, etc.
