PE plastic film

PE film, that is, polyethylene film, refers to the film produced with PE film. PE film has moisture resistance and low moisture permeability. Polyethylene film (PE) can produce low-density, medium-density, high-density polyethylene and cross-linked polyethylene according to different manufacturing methods and control methods.

Production Process

Blowing machine is a mechanical device that heats and melts PE plastic particles and then blows into a film. First, the dried polyethylene particles are added into the lower hopper, and the weight of the particles enters the screw from the hopper. When the pellets contact the screw bevel, the rotating bevel faces the plastic and generates a thrust perpendicular to the bevel. The plastic particles move forward. During the process, due to the friction between the plastic and the screw, the plastic and the barrel, and the collision and friction between the particles, it also gradually melts due to the external heating of the barrel. The molten plastic comes out of the die head through the filter screen of the machine head, and is blown out and cooled by the air ring. After being pressed by the herringbone plate, it is taken up by the traction roller to wind the finished film into a tube.
