The CPP film, a cast polypropylene film, is also called an unstretched polypropylene film.
CPP is a polypropylene (PP) film produced by a cast extrusion process in the plastics industry. This type of film is different from BOPP (biaxially-oriented polypropylene) film and is a non-oriented film. Strictly speaking, the CPP film has only a certain-orientation in the machine direction (MD) direction, mainly due to the nature of the process. Excellent clarity and finish are formed on the film by rapid cooling on a chill roll.
CPP film is widely used for food packaging, textiles packaging, twist wrapping, floral wrapping, medical and hygiene film, retort packaging, deep freeze application as well as lamination with BOPP or PET film for surface protection with barrier properties.
