A small blown film machine is produced in accordance with the characteristics of the material and widely used in different areas of the membrane. Applicable to all kinds of high-grade packaging film, plastic film, protective film, etc.. This film is because of its good barrier properties, preservation, anti moisture, anti frost, oxygen, oil resistance, can be widely used in light and heavy bags. Such as a variety of fresh fruits, meat products, pickles, fresh milk, liquid drinks, medical supplies, etc.. So those materials suitable for plastic film blowing machine?
Linear low density polyethylene (1)
Linear low density polyethylene, different from the general structure of low density polyethylene, because there is no long chain. Linearity of linear low density polyethylene depends on the production process of linear low density polyethylene and low density polyethylene. Linear low density polyethylene at high temperature and pressure, usually produced by the addition of high olefins to ethylene. The polymerization method of linear low density polyethylene (LDPE) polymer is more narrow than that of ordinary low density polyethylene, and the rheological properties of linear structure make it different.
2) high density polyethylene
High density polyethylene, which is a high crystallinity, non-polar thermoplastic resin. The appearance of high density polyethylene type is milky white, refined to a certain degree of translucent cross-section. PE has excellent resistance to most of the chemicals used in life and industry. Chemical erosion of certain kinds of chemicals. The polymer is not hygroscopic, has good water vapor and can be used for packaging. High performance polyethylene with high dielectric strength and high dielectric strength make it very useful in wires and cables. To the high molecular weight class has excellent impact resistance, at room temperature, even at - 40 F high temperature is so.
3) low density polyethylene
Low density polyethylene (PE) is a kind of plastic material, which is suitable for the forming process of thermoplastic. Low density polyethylene film products important applications, can also be used for injection molding products, medical equipment, pharmaceutical and food packaging materials, hollow blow molding products, etc..
