High speed film blowing unit used for blowing high-low pressure polyethylene, the products are widely used in composite film, packaging film, agricultural covering film, textiles, clothing bag or film and other packaging, main motor adopts frequency control of motor speed, increase the stability of the host speed, and power saving 30%, screw cylinder aluminum 38 chrome molybdenum, diameter nitriding treatment, drawing frame adopts the lift, no matter big and small size film can make the best cooling effect.

Low density polyethylene film is generally made of blow - and - flow. The thickness of the polyethylene film is uniform, but it is seldom used because of the high price. Blow - plastic polyethylene film is made by blow molding machine blown by blow molding machine, the cost is low, so the application is most extensive.

Low density polyethylene film is a semi-transparent, glossy and soft film with excellent chemical stability, heat sealing, water resistance and moisture resistance. It can be refrigerated and can be boiled. Its main drawback is that of oxygen barrier property is bad, often used in the inner membrane of composite flexible packaging material, and is currently the most widely used, the dosage is one of the biggest plastic packaging film, more than about 40% of plastic packaging film consumption.

The film made of film blowing machine is good for its barrier properties, fresh, moisture resistant, frost proof, oxygen resistant, oil resistant, widely used in weight packaging. It is widely used in such fields as fresh fruit, meat, pickles, fresh milk, liquid beverage and medical supplies. But it's not made from plastic, it's made of plastic particles. The group is suitable for plastic film such as low density polyethylene (LDPE), HDPE, and linear low density (LLDPE).

The application of the dalian blown film unit is widely used, and the performance characteristics of the film blower are simply introduced: the blowing machine can be configured to rotate the machine head according to the user's needs; The screw of the film blowing machine has a large diameter ratio, strong plasticizing ability, uniform temperature distribution, automatic temperature control, and good performance of the thin film and polished products. The machine has a compact structure, stable operation, single arm architecture, economical and practical, integrated and adjustable traction equipment. The film blowing machine adopts the advanced frequency conversion technology to save energy. The curling form of the blowing machine is varied and optional. The screw of the blowing machine adopts the most advanced alloy spraying technology, which is highly processed, with higher hardness, better corrosion resistance and long life, and two to three times the life of the nitrogen treated screw.
