What are PET bottles made of

PET (polyethylene terephthalate) bottles are made from a type of plastic that is derived from crude oil. The plastic is formed through a polymerization process that involves combining ethylene glycol and terephthalic acid. The resulting polymer is then melted and formed into the shape of a bottle through a process called blow molding.

PET is a lightweight, durable, and transparent plastic that is commonly used for beverage and food packaging. It is also recyclable, making it an environmentally-friendly option for packaging.
