[0002] Plastic film generally refers to films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging and as a coating layer. Plastic packaging and plastic packaging products occupy an increasingly larger share of the market, especially composite plastic flexible packaging, which has been widely used in the fields of food, medicine, and chemical industry. Among them, food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, steamed food packaging, fast food packaging, etc. These products have brought great convenience to people's lives. Among the many types of plastic films, polyethylene film is widely used as a raw material for packaging bags, food bags, and various containers due to its colorless, tasteless, odorless, translucent, non-toxic, and insulating properties.
