The extruder, barrel and screw of this unit are all made of high-quality alloy steel with tight nitriding treatment and precise processing, which has the best hardness and corrosion resistance. The specially designed screw has high output and good plasticization. It is suitable for blowing plastic films such as low-density polyethylene (LDPE), high-density polyethylene (HDPE), linear low-density polyethylene (LLDPE), etc. It is widely used in civil and industrial packaging such as food, clothing, garbage bags, and vest bags.
