The blown film unit is suitable for blowing plastic films such as low density polyethylene (LDPE), high density polyethylene (HDPE) and linear low density (LLDPE). It is widely used in fruits, food, clothing, textiles, strain cultivation, daily necessities, etc. The advantages of the screw for the internal and external packaging of civil and industrial products are as follows:
1. The blown film machine screw adopts the advanced alloy spraying technology. After precision machining, the hardness is higher, the corrosion resistance is better, and the service life is longer. It is 2~3 times of the life of the nitriding treatment screw;
2. The long diameter to diameter ratio of the screw is large, the plasticizing ability is strong, the temperature distribution is uniform, the automatic temperature control, and the blown film bright and uniform product has good performance;
3. The whole machine is compact in structure, stable in operation, single-arm structure, economical and practical, and the traction device is integrated and can be adjusted and lifted;
4. Adopt advanced frequency conversion technology to achieve high efficiency and energy saving;f
5, the variety of curls can be arbitrarily selected;
6, the rotating head can be configured according to user needs.
