It is produced by using imported linear polyethylene LLDPE resin and special tackifier special additives proportion formula. It can produce multifunctional stretch film for hand use, resistance type machine use, pre-stretch type machine use, anti-ultraviolet, anti-static and anti-rust. It has the following advantages Using double-layer co-extrusion equipment, the compressed stretch film can maximize the characteristics of each polymer, and its transparency, tensile strength, and perforation resistance are the best when it reaches the melting point. status. 2. It has good stretch-ability, good transparency and uniform thickness. 3. It has longitudinal extensibility, good resilience, good transverse tear resistance, and excellent self-adhesive lap. 4. It is an environmentally friendly and recyclable material, tasteless, non-toxic, and can directly package food. 5. It can manufacture single-sided viscous products, reduce the noise emitted during winding and stretching, and reduce dust and sand during transportation and storage.
