Anti Fog CPP Film; Effectively Reduce Water Mist Accumulation and Ensure Product Aesthetics

CPP film [1] is cast POLYPROPYLENE film, also known as unstretched polypropylene film, which can be divided into General CPP (GCPP) film and aluminized CPP (Metalize CPP) film according to different uses. MCPP) film and Retort GRADE CPP (Retort CPP, RCPP) film, etc.

CPP is polypropylene (PP) film produced by flow extrusion process in plastic industry. This kind of film is different from BOPP(bidirectional polypropylene) film and belongs to non-oriented film. Strictly speaking, CPP films only have a certain orientation in the longitudinal (MD) direction, mainly due to the nature of the process. Excellent clarity and finish is achieved on the film by rapid cooling on the cold casting roll.

CPP-C115 is a three layers co-extrusion cast polypropylene film.This Film has exellent heat sealing performance and wide heat sealing range,It can be used for packing food,medicine and commodity in the form of multi-compartment bags.
