Overview
Casting polypropylene (CPP) film materials, are used in the surface and internal layers of CPP film. CPP films produced using these resin are characterized by high transparence, 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.
Application
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.
Package, Storage & Transprtation
The resin is packaged in internally film-coated polypropylene woven bags, FFS bags or container bags and the net weight is 25Kg/bag or 700Kg/bag. The resin should be stored in a drafty, dry warehouse and away from fire and direct sunlight. It should not be piled up in the open air. During transportation, the material should not be exposed to strong sunlight or rain and should not be transported together with sand, soil, scrap metal, coal or glass. Transportation together with toxic, corrosive and flammable substance is strictly prohibited.
