Polyethylene (PE) is a lightweight, durable thermoplastic with variable crystalline structure. PE is one of the most widely produced plastics in the world (tens of millions of tons are produced worldwide each year). It 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 ethene) monomer. Polyethylene chemical formula is (C2H4)n.

Polyethylene refers to a group of thermoplastic homopolymers made up of molecular chains consisting of multiple repeating ethene (IUPC name “ethene”) monomers. Polyethylene and its variants are the most commonly used commodity plastics. Polyethylene is typically used for plastic bags, food/drink containers, and medical applications like knee joints. Polyethylene’s chemical structure consists of repeated monomers made from carbon and hydrogen atoms. There are generally four common types of polyethylene: Ultra- High Molecular Weight Polyethylene (UHMWPE), High-Density Polythene (HDPE), Low-Density Polyethylene (LDPE), and Linear Low-Density Polyethylene (LLDPE).
