Chinese plastics blown film line manufacturers commonly used blown film material unit

Blown film machine is 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 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, after nitriding process, drawing frame adopts lift, no matter big and small size film can make the best cooling effect;

Blown film machine, blown film is often do goods transport, food, packaging, preservation, biotechnology and other industry products, the quality of the film blowing machine and blowing film technology determines the quality of the film forming.So a good performance in the film blowing machine in the process of production of thin films showed good ability to adapt the market, improve the production efficiency at the same time, provide convenience for the people and promote the harmonious development of society.

（1）HDPE

HDPE (High Density Polyethylene, referred to as "HDPE"), is a kind of High crystallinity, nonpolar thermoplastic resin.Square one HDPE appearance has milk-white, in a small cross section in a certain degree of translucent.PE has excellent resistance to most of the life and the characteristics of industrial chemicals.Some kinds of chemicals can produce chemical corrosion, such as corrosive oxidant (nitric acid), aromatics (xylene) and halogenated hydrocarbon (CTC).The polymer is not hygroscopic and has a good waterproof steam, can be used for packaging purposes.HDPE has the very good performance, especially high insulation dielectric strength, make it very suitable for wire and cable.In the level of high molecular weight has excellent impact resistance, even at room temperature under 40 f low temperature are so.

（2）LLDPE

Linear low density polyethylene, structurally different from general of low density polyethylene, because there is no long branches chain.LLDPE linearity depends on the different production process of LLDPE and LDPE.LLDPE under lower temperature and pressure, usually by a olefins such as ethylene and senior butene, hexene or octene copolymerization and generated.Copolymerization process of LLDPE polymers with narrow molecular weight distribution, better than the average LDPE with linear structure at the same time make its have different rheological properties.

（3）LDPE

Low density polyethylene degrees polyethylene (LDPE) is a kind of plastic material, it is suitable for thermoplastic processing a variety of molding process, forming good workability.LDPE main purpose is for thin film product, also used in plastic injection products, medical devices, pharmaceutical and food packaging materials, hollow blow molding products, etc.

This film is composed of a translucent nylon membrane, the film is almost transparent, good permeability, on the interlayer containing a certain amount of sand syrup, gently coated surfaces, it is a harmless film must ensure that the environmental protection, at the same time a strong water permeability, absorb the fruit and vegetable juice, the purpose of keeping fresh.The special raw material need film blowing machine has high traction and drawing ability, to ensure that the product film tenacity breathable.
