Over 60 million tonnes of poly(ethene), often known as polyethylene and polythene, is manufactured each year making it the world's most important plastic. Its uses include film, packaging and containers, from bottles to buckets.ses of poly(ethene) (polyethylene). -3) and linear low density (LLDPE) (ca 0.915-0.940 g cm -3) and high density (HDPE) (ca 0.940-0.965 g cm -3). The LDPE or LLDPE form is preferred for film packaging and for electrical insulation.
Oxidized Polyethylene Wax(OPE) is widely used in processing of packing materials and thermoshrink film as external lubricant. Oxidized Polyethylene Wax(OPE) is used as processing auxiliaries for PVC shapes, pipes and plates to increase the surface smoothness of the processed products with an amount of 0.3-0.5%. method of preparation of oxidized polyethylene waxes, which have many applications such as in plastics, rubber, leather, paper, inks and textile, etc. was developed.
