Commodity Plastics
The more commonly used thermoplastic materials are known as commodity plastics as they are traded and used in great quantities. Examples are polystyrene (PS), polyvinyl chloride (PVC), polypropylene (PP) and polyethylene (PE).
Typical applications for commodity plastics are high production volume products such as ‘polythene’ bags (made from polyethylene), vacuum-formed food packaging (low density polyethylene), disposable drinking cups (high-impact polystyrene) and window frames/wire insulation (PVC).

Famous quotes containing the word commodity:
“There used to be a thing or a commodity we put great store by. It was called the People. Find out where the People have gone. I don’t mean the square-eyed toothpaste-and-hair-dye people or the new-car-or-bust people, or the success-and-coronary people. Maybe they never existed, but if there ever were the People, that’s the commodity the Declaration was talking about, and Mr. Lincoln.”
—John Steinbeck (1902–1968)
