Coroplast (corrugated plastic)

This is a corrugated plastic material, much like cardboard. It is a very inexpensive option. Often used as "disposable signs" that are placed around the city not expecting to be returned. Also used as political signs. Cut vinyl is the best solution for Coroplast, but there is a smooth version which can accept printed vinyl well. Coroplast comes in all sizes but most commonly is found in 18"x24" in white or yellow.
