SJ50/55/60/65/80 PE Film Blowing Extrusion Machine - Film Blowing Machine_Bag Making Machine

Useful:
This machine is suitable for blowing high-density polyethylene (HDPE), low density polyethylene (LDPE)

and linear low density polyethylene (LLDPE) plastic film, widely used in food, clothing, textiles, daily use

articles and industrial products such as packaging. Formula can be raw materials through production

pearl film and degradation film.
Features:
1 screw and barrel are used 38CRMOALA alloy by nitrogen treatment and precision machining, high

hardness, corrosion resistance and durability.
2 die hard chrome plating, the screw mandrel type structure, the molten material out of uniform, blown

film has fine finishing: blower is of labyrinth structure, even air output. Unit adopts lifting type according to

different process requirements for lift adjustment.
3. Coiling unit adopts pressure friction rewinding or center rewinding, driven by torque motor, rewinding and

changing easy.
