Blown film machine is a kind of plastic machinery, the main works: add dry polyethylene particles to the hopper, depend on the weight of the particles themselves from the hopper into the screw, when the aggregate after contact with thread oblique edge rotating slant edge face plastic produce and inclined faces the vertical edges of thrust, plastic particles pushed forward.

During the course of the process, the friction between the plastic and the screw, the friction between the plastic and the cylinder, and the collision friction between the particles are also gradually dissolved due to the external heating of the cylinder. The molten plastic is filtered through the head of the machine to remove the impurities from the die, through the wind ring cooling, blowing through the human word board, traction roll, and winding the finished film into a cylinder.

Dalian plastics blown film machine in order to satisfy the customers in the process of production of plastic film packaging materials need some special function, will be a variety of characteristics of materials (e.g., breathe freely, waterproof, thermal insulation, toughness, etc.) and co-extrusion blown film together, form a multi-functional plastic film, our company after many years of research and practice development. A multi-layer co-extrusion film blowing machine was developed. The purpose is to use the advantages of various materials, to avoid the disadvantages of single material or single-layer blown film machine, to provide customers with the market competitive film blowing machine

In the multilayer, such as PP and PE film unit, it is the combination of the characteristics of PP material hardness and the high brightness of PE materials that produce two films of combination of characteristics. The multi-layer co-extruder film machine is divided into several kinds, such as the two-story coextruder, the three-layer co-extrusion blower, the five-layer coextruder and the seven layers of the film machine, etc.

Five layers co-extrusion blown film line, mainly is suitable for the HDPE, LDPE, LLDPE, EVA has gas barrier properties of resin, such as the production of thin film is mainly used for packaging, high-grade food bag, vacuum bag, liquid packaging bags and other packaging materials, incense, fresh, anti-corrosion, airtight, extend the shelf life of the packing.
