Polyethylene (PE) is a thermoplastic polymer with a variable crystalline structure and a vast range of applications depending on the particular type. PE is one of the most widely produced plastics in the world (tens of millions of tons are produced worldwide each year). Polyethylene is used in applications ranging for films, tubes, plastic parts, laminates, etc. in several markets (packaging, automotive, electrical, etc)

Polyethylene is made from the polymerization of ethylene (or ethane) monomer. PE belongs to polyolefin family of polymers and is classified by its density and branching. The most common types of polyethylene are
