PE film production process

The film blowing machine is a mechanical equipment that heats and melts PE plastic particles and then blows them into a film. First, put the dry polyethylene particles into the lower hopper, and enter the screw from the hopper by the weight of the particles. The plastic particles move forward. In the process of moving, 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 is removed from the die head through the filter screen of the machine head, and then comes out of the die orifice. After being inflated and cooled by the air ring, the molten plastic is pressed by the herringbone plate, and the finished film is rolled into a tube by the traction roller.
