[0002] PE film, namely polyethylene film, refers to a film produced by PE particles. PE film has moisture resistance and low moisture permeability. According to different manufacturing methods and control means, polyethylene film (PE) can manufacture products with different properties such as low-density, medium-density, high-density polyethylene and cross-linked polyethylene. During traditional preparation, when the film thickness needs to be changed due to the change of product variety, the appropriate opening die must be replaced.
