Use: It is used for blowing the various plastic films of low density polyethylene (LDPE), high density polyethylene (HDPE) and linear low density polyethylene (LLDPE) etc. which are widely used for packing liquid industrial products garment and textile etc. and printing lamination.
Characteristics: The cylinder and the screw stems of the extruder are made of high quality alloy steel with optimum hardness and strong corrosion resistance after nitrogen treatment and precision finishing. The auxiliary machine has a plat from working table for making operation easy and is equipped with bubble stabilizing ring. Double- rolling and double cutting unit adopts torque motor to motor to keep proper tension and make even and roll-changing easy.
