PET Processing - Extrusion

Zone overview hereIn extrusion, most PET is processed into sheet for food packaging applications. The PET sheet is subsquently thermoformed--in some cases in line with the extrusion process--into products such as drinking cups, trays, clam shell containers and the like. Industrial applications for PET include point of purchase signs, display fixures and glazing. Gylcol-modified PET (PETG) is commonly used in sheet structures used to package medical devices because it can stand up to gamma irradiation.
