Film blowing machine is to heat plastic particles melt and then blow into a film. There are many kinds of film blowing machine, PE,POF,PVC and so on. With the new particles blown out is a new material, color is equal, clean, the bag stretched well.
The film blowing machine will dry polyethylene particles into the hopper, by the weight of the particles themselves from the hopper into the screw, when the particle and the threaded oblique edge contact, the rotating oblique edge to the plastic and the oblique edge of the vertical thrust, the plastic particles forward, due to the friction between the plastic and the screw, plastic and the cylinder and the collision friction between the particles, At the same time, it gradually melts due to the external heating of the cylinder. The molten plastic is filtered through the head to remove impurities from the die mouth, cooled by the air ring, blown through the herringbone plate, traction rollers, and rolled into the finished film into a cylinder.
