Winding machine (also known as elastic film, stretching retractable film, self-mucosa) is a kind of soft film with high transparency and elasticity. Plastic packaging film equipment has high tensile strength, tear strength and good penetration resistance. A new type of packaging material is made by using imported linear low density polyethylene (LLDPE) as the main raw material and adding a few accessories to mix evenly, melting and plasticizing through extrusion system, then using single layer, double layer or three layer co-extrusion salivation process through die and forming die. Plastic packaging film equipment has good vertical and horizontal two-way cold stretching characteristics, and has greater retraction, lasting tightening force, one-sided or two-sided self-stickiness, and appropriate air permeability and moisture permeability. Depending on its own stickiness.

Wrapping film machine is mainly used for tray transport packaging, cluster packaging of large or various scattered items, food refrigeration packaging of household and supermarket. It can also pack household appliances, precision instruments, bicycles, motorcycles, high-grade furniture and other products. It can keep the tension of packaging items for a long time without loosening. As a new type of packaging material, winding film machine has simple packaging technology, which can be packaged manually and mechanically. The winding film machine simplifies the packaging procedure and equipment, has good safety performance, and has the advantages of waterproof, dust-proof and good 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.
