Coroplast® is a brand name for a polypropylene product that has become so successful that it is generically used for the product at large today. Much like a plastic version of cardboard, it is lightweight (hollow structure), non-toxic, waterproof, shockproof, long-lasting material that resists corrosion. Compared with cardboard, Coroplast® has the advantages of being waterproof and colorfast, with an amazing range of colors and thicknesses available.
Coroplast® is sturdy, light, resilient, inexpensive and easy to cut and work with, making it ideal for: indoor/outdoor signage, packaging, light industry guarding, crates/boxes, partitions, animal cages and many other creative uses, including a popular on-line folding kayak.
