Model Number

SJ45

They are 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 industrial products, garments and food and for covering farmland.

Characteristics: The cylinders and the screw stems of the above extruders are made of high-quality alloy steel with optimum hardness and strong corrosion resistance after precision finishing and nitrogen treatment. The auxiliary machine has a platform working table for making operation easy. The coiling unit adopts torque motor to keep proper tension and make rolling even and roll-changing easy.
