Characteristics:
It is used for bolwing polypropylene(PP)and also for blowing high/low density polyethylene(HDPE,LDPE)tube which is widely used for packing food,garments,textile,daily necessities and industrial products etc. The cylinder and the screw of extruter are made of high quality alloy steel with optimum hardenss and strong corrosion resistance after nitrogenization treatment.The extruder can be lifted up to 3 meters according to the technological requirements.Mode of film blowing .adopts bottom blowing. The coiling device adopts torque motor to keep proper tension and make rewinding even and roll-chang convenient.
