Q. What is the most used plastic in the world?

Answer

Polyethylene Terephthalate (PET or PETE) is one of the most commonly used plastic owing to the fact that it is lightweight, strong, and typically transparent. It is often used in food packaging and fabrics (polyester) and we commonly see them around us as beverage bottles, food bottles and jars, like those used for salad dressing, peanut butter, honey, etc. and as polyester clothing or rope.
