High and low pressure ultra-thin blown film machine

Purpose:
This unit is suitable for blowing high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE) plastic films, which are widely used for packaging household and industrial products such as food, clothing, textiles, and daily necessities.
characteristic:
1. The screw and barrel are both made of 38CRMOALA alloy steel, which has undergone nitriding treatment and precision machining. It has high hardness, strong corrosion resistance, and durability;
2. The die head is plated with hard chromium, and its structure is spiral core shaft type. The extruded molten material is uniform, and the blown film has good smoothness;
3. The winding device adopts pressure controlled winding or center winding, and is adjusted by a torque motor. The winding is smooth and easy to change.
