This production line mainly uses LLDPE (linear low-density polyethylene) as the main raw material, and produces self-adhesive single-sided or double-sided two-layer or three-layer co extruded stretch wrap film through extrusion. The co extruded wrap film produced has higher tensile strength, puncture resistance, and impact resistance than single-layer wrap film, while also having good shrinkage memory and self adhesiveness.
