The winding film produced by winding machine (also known as elastic film, stretching retractable film, self-mucosa) is a kind of soft film with high transparency and elasticity. Film winding machine has high tensile strength, tear strength and good penetration resistance. A new packaging material is made of imported linear low density polyethylene (LLDPE) as the main raw material, mixed with a few accessories evenly, melted and plasticized by extrusion system, and then used single layer, double layer or three layer co-extrusion salivation process through die and forming die. Winding film machine has good longitudinal and transverse two-way cold stretching characteristics, and has greater retraction, lasting tightening force, one-sided or two-sided self-stickiness, and suitable air and moisture permeability. Depending on its own stickiness.

The winding film machine is mainly used for tray transport packaging, cluster packaging of large or various scattered items, food refrigeration packaging of families and supermarkets, and packaging of household appliances, precision instruments, bicycles, motorcycles, high-grade furniture, etc. It can keep the tension of packaging items for a long time without loosening. As a new packaging material, PE wrapping film has simple packaging technology, which can be packaged manually and mechanically. It simplifies the packaging procedure and equipment, has good safety performance, and has the advantages of waterproof, dust-proof, visual appearance. Winding film machine is a kind of green environmental protection material, non-toxic and harmless, widely used in food, beverage, medicine and other industries.
