Plasticor Corrugated Boards

Plasticor is corrugated polypropylene boards. It is much like corrugated cardboard in the weight, thickness, the way it folds and the way it cuts, but it is made of plastic which makes it insect and water resistant. Great for making storage for artwork and papers; just use 3M colored plastic tape to connect pieces together making sleeves and boxes. Nothing works better for making yard graphics and lightweight outdoor signs - just use adhesive sign lettering and plastic tape to achieve a real professional look. 4mm thick.
