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.
