Polypropylene (PP), also known as polypropene is a type of fibre. It can either be a plastic or fabric. As a plastic it is opaque and often brightly colored. Sometimes it is very tough. But can also be very weak as well.

It is usually formed into a thin thread that is woven into a special strap that can be found on backpacks, bags, and other things.

In 2008, the global market for polypropylene had a volume of 45.1 million metric tons, which led to a turnover of about $65 billion (~ €47.4 billion).[1]
