Pe shrink film extruder

The film blowing machine heats and melts the plastic particles and blows them into a film. High and low-pressure polyethylene dual-purpose film blowing machine unit is used to blow various plastic films such as low-density polyethylene (LDPE), high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE). The films can be widely applied to packaging for industrial products, textiles, apparel and food and agricultural coverage. The cylinders and screw rods of extruders in mentioned models are all made from high-quality alloy steel through precision machining and nitriding, so as to ensure optimal hardness and corrosion resistance. The specially designed screw has high output and good plasticization. The auxiliary extruder is provided with a platform rail worktable to be operated more conveniently. The winding device adopts torque motor as the power to keep suitable tension, orderly winding and convenient roll replacement.

Features:

It is a heavy duty construction.

It is easy to operate.

It reduces fuel consumption, which is economic and eco-friendly.

Production process and production principle:

The dried polyethylene particles are added into the lower hopper, and enter the screw from the hopper by the weight of the particles themselves. When the pellets are in contact with the helical bevel of the thread, the rotating bevel faces the plastic to produce a thrust perpendicular to the beveled surface, and the plastic particles are moving forward. During the transition, due to the friction between the plastic and the screw, the plastic and the barrel, and the collision between the particles. It is also gradually melted due to the external heating of the barrel. The molten plastic is filtered by the machine head to remove impurities from the die, cooled by the air ring, inflated through the herringbone plate, the traction roller, and wound to wind the finished film into a cylinder.

Main structure: 

It mainly consists of extruder, head, die, cooling device, foam stabilizer, herringbone plate, traction roller, coiling device, etc.

Uses: 

The film blowing machine produces a film suitable for a variety of high-grade film packaging. The film is widely used for light and heavy packaging because of its good barrier property, preservation, moisture resistance, frost resistance, oxygen barrier and oil resistance, such as a variety of fresh fruit, meat food, pickles, fresh milk, liquid beverages, medical supplies and so on.
