What are polypropylene bags made out of?

#5 Polypropylene Poly Bags Although also in the family of polyolefins, polypropylene is made from the polymerization of the olefin propylene. It’s second to polyethylene as one of the most-used poly bag types, and is growing in popularity due to its useful applications in packaging.

Which is more expensive polyethylene or polypropylene?
