Main characteristics and recycling of polyethylene packaging material
polyethylene packaging material have low density and high specific strength, which can achieve high packaging yield, that is, "package volume per unit mass or packaging area. Most plastics have good chemical resistance, good acid and alkali resistance. Resistant to all types of organic solvents, long-term placement, no oxidation.
polyethylene packaging material are easy to form, and the required molding energy consumption is lower than that of steel and other metal materials; and also has good transparency and easy coloring; has good strength, high strength per unit weight, impact resistance, and easy modification. In addition, it has low processing cost and excellent insulation.
polyethylene packaging material continue to replace disposable paper packaging materials in the original industrial system with its excellent multi-cycle characteristics. The development of new material grades and high-performance, versatile materials has made it possible to reduce weight reduction.
The lean manufacturing and automation of polyethylene packaging material is to properly implement the three requirements of energy saving, clean production and waste production from the source of manufacture. At the same time, it can fully solve the problem of overcapacity in the existing plastic packaging industry.
