Polyethylene terephthalate is one of the most important thermoplastics in the polyester family with about 6% of the total amount of plastics produced.

The invention of the two Englishmen John Rex Whinfield and J. T. Dickson. In 1941, in the laboratories of the textile company Calico Printers Association in Accrington, Great Britain, they succeeded for the first time in the production of a polyester from ethylene glycol and terephthalic acid.

Originally used only for fibers, today about one quarter of the quantity produced is used for packaging and semi-finished products.
