Final answer:
Polyethylene Terephthalate (PET / PETE) is a type of plastic commonly used in fibers, containers, and engineering resins.
Step-by-step explanation:
Polyethylene Terephthalate (PET / PETE) is a type of plastic.
Polyethylene terephthalate (PET) is the most common thermoplastic polymer resin of the polyester family. It is used in fibers for clothing, containers for liquids and foods, and in combination with glass fiber for engineering resins.
The majority of the world's PET production is for synthetic fibers and bottle production. Polyester makes up about 18% of world polymer production and is the fourth-most-produced polymer after polyethylene (PE) polypropylene (PP) and polyvinyl chloride (PVC).
