ABA film blower is gradually melted by extrusion, friction, heating and external heating. The melted raw materials are extruded from the die mouth, then blown, cooled by the air ring, pulled up by the traction frame, pulled up by the traction roll, and then rolled up by the reeling frame to form the film drum material. There are many kinds of film blowing machines, such as PE, POF, PVC and so on. The new material is blown out with brand-new particles. The color is uniform, clean and the bag is well stretched.
The main structure of film blower is mainly composed of extruder, die, cooling device, foam holder, herringbone, traction roll and coiling device. 1: Extruder, extruder is mainly composed of screw, barrel feeder, deceleration and driving motor. New material is blown out with brand-new particles, with uniform color, clean and good bag stretching.
Others use recycled plastic bags to make particles, which are generally called used materials. When they are made into particles, they are usually grey. When they are made into bags, they usually need to add pigments. The bags are uneven in color, brittle and fragile, and the price is low. When the grain is in contact with the screw bevel, the rotating bevel produces a vertical thrust on the plastics, pushing the plastics particles forward.
In the process of moving, due to the friction between plastic and screw, plastic and barrel, and collision friction between particles, the film blower produces film suitable for various high-grade film packaging. Because of its good barrier, fresh-keeping, moisture-proof, frost-proof, oxygen-proof and oil-proof, the film can be widely used in light and heavy packaging. Such as all kinds of fresh fruits, meat products, pickles, fresh milk, liquid drinks, medical supplies and so on.
