Coraplast, is a light self supporting, hollow core ribbed material much like cardboard in design. Coraplast is manufactured from impact grade PVC, polypropylene or polyethylene, depending on the manufacturer. Coraplast competes against many traditional materials where benefits of light weight strength, weather resistance, chemical resistance and durability under repeat abuses are important: Coraplast is a cost effective alternative.

10mm coraplast sheets are a durable lightweight alternative to plywood, metal or solid plastic for graphics applications. A 48" x 96" sheet weights only 13 lbs. Additives are available fro static control, long term ultra violet protection and to reduce flammability. Coraplast comes in 12 standard colors.
