Plastic packaging and plastic packaging products occupy an increasingly larger share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, frozen food packaging, steamed food packaging, fast food packaging, etc. These products have brought great convenience to people's lives.

[0003] The existing plastic film molding requires molten plastic and then extruded. Due to the design of the extrusion die and the influence of process parameters, the thickness of the film may vary to a certain extent, resulting in thinner or thicker thickness in some areas, which may affect the performance and consistency of the film. The width of the formed film will be uneven. Films with uneven widths may cause some products to fail to meet the requirements and be discarded, resulting in a waste of resources and energy. In addition, the film may shift during the winding process. The shift will cause the edges of the film to be misaligned or uneven when it is wound, affecting the overall appearance and quality of the product.
