[0002] CPP film is cast polypropylene film, also known as unstretched polypropylene film. It can be divided into general CPP film, aluminized grade CPP film and cooking grade CPP film according to different uses. CPP is a polypropylene (PP) film produced by cast extrusion process in the plastic industry. This type of film is different from BOPP (bidirectional polypropylene) film and is a non-oriented film. Strictly speaking, CPP film has a certain orientation only in the longitudinal (MD) direction, mainly due to the nature of the process. Through rapid cooling on the cold casting roller, excellent clarity and smoothness are formed on the film.
