Soft CPP Film; Low Sealing Temperature; Suitable for High-Speed Packaging; High Friction Coefficient; Cast Polypropylene Film for Packing;

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-C117 is a three layers co-extrusion cast polypropylene film.This Film is a Semi Retort CPP which has high impact strenth and heat seal easy peel off without scrap,It can be retorted under condition of 121-125ºC,30min for food  packing 

Character
-Heat sealing easy peel off
-retorted  condition : 121-125ºC,30min
-Good heat resistance
