Polyethylene : Types, Uses, Properties, Application & Structure info Polyethylene  or  polythene  (abbreviated  PE ;  IUPAC  name  polyethene  or  poly(methylene) ) is the most common  plastic  in use today. It is a  linear ,  man-made ,  addition ,  homo -polymer, primarily used for  packaging  ( plastic bags ,  plastic films ,  geomembranes , containers including  bottles , etc.). As of 2017, over 100 million  tonnes  of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. [5] [6] Many kinds of polyethylene are known, with most having the  chemical formula  (C 2 H 4 ) n . PE is usually a mixture of similar  polymers  of  ethylene , with various values of  n . It can be  low density  or  high density : low density polyethylene is extrudedusing high pressure (1000-5000 atm) and high tem...
