History of PET Plastic Bottles
Polyethylene terephthalate (PET) is a type of plastic that was first developed in the 1940s. It quickly became a popular material for making fibers, films, and containers because of its strength, clarity, and recyclability. In the 1970s, PET bottles began to be used for packaging carbonated beverages, and they quickly became the standard for this type of packaging.
