Technical Field
The invention relates to the technical field of food packaging, in particular to a CPP (casting polypropylene) bag made by steaming and boiling resistant to puncture.
Background
The CPP film is a cast polypropylene film (also called an unstretched polypropylene film), and may be classified into a General CPP (General CPP, abbreviated as GCPP) film, an aluminized CPP (metal CPP, abbreviated as MCPP) film, a cooking CPP (restore CPP, abbreviated as RCPP) film, and the like according to its use. CPP is a polypropylene (PP) film produced by a cast extrusion process in the plastics industry. The film is different from BOPP (biaxially-oriented polypropylene) film and belongs to a non-oriented film. Strictly speaking, CPP films have some orientation only in the Machine Direction (MD), primarily due to process properties. By rapidly cooling on the chill roll, excellent clarity and finish are formed on the film.
However, the puncture resistance and antistatic property of the conventional CPP film are to be further improved.
