polypropylene
Common packaging plastic
Polypropylene is a synthetic plastic polymer used widely in packaging, textiles, and manufacturing.
It's lightweight, resistant to chemicals and fatigue, and tolerates heat well—qualities that make it common in food containers, carpeting, automotive parts, and reusable bags.
Often abbreviated PP.
