Material
PP
Broad chemical resistance and heat tolerance. The closure material.
What It Is Good At
Hot fill, steam, most solvents, living hinge. Almost every pump and cap is PP.
Where It Stops
Lower gloss, hazier than PET, and it scratches visibly.
Typical Use
Pumps, caps, flip-tops, jars for hot fill.
