What is the purpose of the film wrapping machine?
The stretch film produced by the stretch film machine (also known as elastic film, stretched shrink film, self-adhesive film) is a soft film with high transparency and elasticity. Stretch film machinery has high tensile strength, tear strength and good puncture resistance. Imported linear low-density polyethylene (LLDPE) as the main raw material, a small amount of auxiliary materials are uniformly mixed, melted and plasticized by the extrusion system, and then passed through the machine head and the molding die by a single layer, double layer or three-layer co-extrusion flow system. A new type of packaging material. Stretch film machinery has good vertical and horizontal two-way cold stretching characteristics, and has a large retractability, long-lasting tightening force, single-sided or double-sided self-adhesive, and suitable breathable moisture permeability. Rely on its own stickiness.
