Cast polypropylene film (CPP) cast polypropylene film is cast polypropylene film production process can be divided into ordinary cooking class CPP and CPP are two plastic films, cast polypropylene film excellent in transparency CPP plastic film uniform thickness VMPET aluminized polyester plastic film, and even the performance of vertical and horizontal direction, generally used as the inner layer of the composite film material. Thickness of ordinary CPP film is generally between 25 ~ 50μm CPP aluminized plastic film, and after the OPP composite transparency is good, bright surface, feeling strong, general gift bags are used such materials. This film also has good heat sealability. After biaxially oriented polypropylene film (BOPP) BOPP film is formed from polypropylene pellets by co-extrusion sheet, then stretched both vertical and horizontal directions and prepared. Since the stretch of molecular orientation, so the physical stability of the film, mechanical strength, better air tightness, high transparency and gloss, tough wear, is currently the most widely used printing film, generally a thickness of 20 to 40 μ m, the most widely used is 20 μ m.
