As a plastic it can be made translucent but usually is opaque and often brightly colored. It is tough, and resists many solvents, acids and bases.
It can be formed into a thin thread and woven into a strong strap, often used 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]
