Lifting HDPE LDPE Film Extruder Usage: This film blowing machine is used for blowing the various plastic film of low density polyethylene (LDPE),high density polyethylene (HDPE) and linear low density polyethylene (LLDPE) etc,Which are widely used for packing food,fruit, garments, textile, garbage bag and vest bag other civil and industrial products, etc and for vest bag. Technical description: 1- screw and barrel: The screw and barrel are made of 38CRMOALA high quality alloy steel. It is after fine finishing and nitrided treatment. It has high hardness, strong resistance to corrosion, durable service. 2- Die head: The die head is plated with hard chrome, of screw mandrel type structure it can strengthen the intensity and evenness of plastic film. 3- Rewinder: The rewinder adopts pressure friction rewinding or center rewinding device, which is driven by torque motor. It is even and smooth rewinding and easy roll changing. 4- Lifting device: the lifting device is suitable for various width of film. If the film width is wider, the lifting device can be lift to higher position. If the film width is narrower, the lifting device can be lift to lower position. 5- electric container: the independent electric container is convenient for operation the machine. 6- Frequancy Inverter: the main motor is adjusted by frequancy inverter, the take-up motor is also adjusted by frequancy inverter. 7- optional device: air shaft,auto loader, electric meter calculator, corona, screen changer.
