What is Polyethylene Film?

PE film, polyethylene film, refers to the film produced by PE film. PE film has moisture resistance and low moisture permeability. Polyethylene film (PE) can be manufactured with different properties such as low density, medium density, high density polyethylene and cross-linked polyethylene according to different manufacturing methods and control methods.

PE film is moisture resistant,

Film blowing machine is a mechanical device that heats and melts PE plastic particles and then blows them into a film. First, dry polyethylene particles are added to the lower hopper, and the weight of the particles from the hopper enters the screw. After the pellets contact the threaded bevel, the rotating bevel faces the plastic and generates a thrust perpendicular to the beveled surface. 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 friction between the particles, it also gradually melts due to the external heating of the barrel. The molten plastic passes through the filter screen of the machine head to remove impurities from the die head, and after being blown and cooled by the air ring, it is pressed by a herringbone plate and taken up by a traction roller to roll the finished film into a cylinder.
