Polyethylene: History, Properties & Classification

Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging (plastic bags, plastic films, geomembranes and containers including bottles, cups, jars, folders, etc.). As of 2017, over 100 million tonnes of polyethylene resins are being produced…
