Hot Sale 500mm Width Wrap Stretch Film China Stretch Wrap

                                        Stretch film, also known as stretch film and heat shrink film, is the first in China to produce PVC stretch film with PVC as base material and DOA as plasticizer and self-adhesive effect. Due to environmental protection issues, high cost (relative to PE's high proportion, less unit packaging area), poor stretch-ability, etc., it was gradually eliminated when the domestic production of PE stretch film was started from 1994 to 1995. The PE stretch film first uses EVA as the self-adhesive material, but its cost is high and it has a taste. Later, PIB and VLDPE are used as self-adhesive materials, and the base material is mainly LLDPE. Stretch film can be divided into: PE stretch film, PE stretch stretch film, LLDPE stretch stretch film, PE slit stretch film, etc. 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.
