This unit is used for blowing polypropylene (PP), low density polyethylene (LDPE), linear low density polyethylene (LLDPE) plastic film. It is widely used in the packaging of foodstuffs, garments, garbage bags, undershirt bags and other civil and industrial goods.
The extruder, barrel and screw of this unit are made of high-quality alloy steel, nitriding treatment and precision machining, with high-quality hardness and corrosion resistance, and the special design of the screw has high output and good plasticization. The mainframe adopts frequency conversion speed control, which increases the stability of the mainframe speed control, and the screw barrel is made of 38 chromium molybdenum aluminum, which is nitrided. The rewinding adopts independent center torque rewinding, with rotating touching head to make the blown film effect better.
