Corrugated Plastic
Corrugated plastic is a sheet product made by extruding plastic such that the resulting sheet has plastic surfaces on each side with a connective mesh between the two walls. The result is a lightweight but strong sheet of plastic popular in crafts and in making plastic containers and signs. Corrugated plastic is usually made from polypropylene, though other plastics are also used depending on the required strength and use of the corrugated sheet.
