SJ-45、50、55、60 Low and High Density Polyethylene Film Blowing Machine
-
This unit is used to blow high density polyethylene (HDPE), low density polyethylene (LDPE), and linear low density polyethylene (LLDPE) plastic films. Widely used in the packaging of household and industrial products such as food, clothing, textiles, and daily necessities.。
The extruder, barrel and screw of the unit are made of high-quality alloy steel. After nitriding treatment and precision processing, it has high quality hardness and corrosion resistance. The specially designed screw has high output and good plasticization. The main engine adopts frequency conversion speed regulation, which increases the stability of the main engine speed regulation. The screw barrel adopts 38 chrome molybdenum aluminum, and is nitrided. The traction frame adopts lifting type, which can achieve the cooling effect regardless of blowing large and small size film. optimal. The winding is wound by independent center torque (single or double), and the rotating head makes the film blowing better.
