It has the characteristics of high toughness, tensile resistance and good wear resistance. It is widely used in chemical industry, clothing, packaging, food and other fields. Can be filled, flame retardant, modified, surface can be embossed, frosted. LDPE(high voltage low density polyethylene) is soft, low mechanical strength, melting point is also low, suitable for making film and cable insulation layer. HDPE(low pressure high-density polyethylene) has higher rigidity, higher mechanical strength, and higher melting point
