PET plastic (also called PETE) stands for Polyethylene terephthalate, the chemical name of polyester. PET is a clear, strong and light plastic commonly used in food and beverage packaging, especially soft drinks, juices and water. PET is also popularly used as salad packaging, peanut butter, cooking oil, toothpaste, shampoo, liquid soap. PET with special grade is used as food containers and food trays that can be heated in an oven or microwave.
The basic components of PET are ethylene glycol and terephthalic acid, which are combined to form polymer chains. The PET strands is pulled, cooled and cut in the form of a small pellet. Plastic pellets can be melted and then pulled or printed into several items in various forms as needed.
was first synthesized in America in mid-1940 by the DuPont chemist as a new fiber synthesis. Then DuPont branded “Dacron” for the PET fiber they created. Now, almost half of the world’s fiber synthesis is made from PET, which is referred to as “polyester” when used to make fiber or fiber yarns. When used for containers and other necessities, it is called PET or PET resin.
In the late 1950s, researchers found a way to pull PET sheets from two sides to create a PET membrane, which is now commonly used for video, photo and membrane packaging. In the early 1970s, the technology for creating bottles by pulling and blowing PET was discovered. The PET bottle was patented in 1973.
PET plastic can be recycled to make PET a resource that can be continually updated compared to glass, aluminum and other materials for containers. PET recycling code is number 1.
