This unit is used for blowing high density polyethylene (HDPE), low density polyethylene (LDPE), and linear low density polyethylene (LLDPE) plastic films. Widely used in food, clothing, textiles, daily necessities and other civilian goods and industrial products packaging.
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 specially designed screw has high output and good plasticization. The host adopts frequency conversion speed control, which increases the stability of the host’s speed control, and the screw barrel adopts 38 chrome molybdenum aluminum with nitriding treatment, and the traction frame adopts lifting type, so that the cooling effect can be optimized regardless of blowing large or small-size films. The rewinding adopts independent big rubber rollers to rely on rewinding (single rewinding or double rewinding), and it can open side and side rewinding device, with rotating touching head to make the effect of film blowing better.
