This production line uses LLDPE (linear low-density polyethylene) as the main raw material, employing several different grades of resin, to produce self-adhesive single-sided or double-sided three-layer or five-layer stretch wrap film through an extruder.

This production line uses a rate plasticizing screw, combined with advanced production processes and technologies to produce multi-layer co-extruded barrier films, with an accurate extrusion control system and an infrared layer detection system to ensure precise control of the total thickness and interlayer ratio of the products.
