▎ 摘　　要

NOVELTY - Three-layer co-extruded antistatic polyethylene film comprises high-toughness inner wall layer, a middle high-toughness inner wall layer, and a scratch-resistant outer wall layer that are sequentially wrapped from the inside to the outside. The mass ratio of the high-toughness inner wall layer material, the middle compression layer material and the scratch-resistant outer wall layer material is 3:4:3. The high-toughness inner wall layer material, the middle compression layer material and the scratch-resistant outer wall layer material all contain an antistatic agent. USE - Three-layer co-extruded antistatic polyethylene film for packaging materials. ADVANTAGE - The three-layer co-extruded antistatic polyethylene film, which has good scratch resistance, pressure resistance and impact resistance, and effectively improves the mechanical strength of the three-layer co-extruded antistatic polyethylene film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a three-layer co-extruded antistatic polyethylene film, which involves: (A) weighing and adding raw materials to the inner, middle and outer film blowing devices in sequence, according to the order in which the high-toughness inner wall layer, the middle compression layer and the scratch-resistant outer wall layer are covered from the inside to the outside; and (B) controlling the temperature of each section of the outer, middle and inner zones of the film blowing device to 200 degrees C, and adjusting the screw speed of the main machine of the film blowing device to 250r/min, traction speed is 8m/min, the inflation ratio is 4, and the three-layer co-extrusion blow molding can prepare the three-layer co-extrusion antistatic polyethylene film.
