Coroplast is a corrugated plastic substrate made from thin polypropylene plastic sheeting. Think of it as corrugated cardboard made from plastic. Coroplast is ideal for indoor and outdoor applications. It is tougher than corrugated fiberboard and lighter than extruded plastic sheet. It is waterproof and stain-resistant.


  • One of the most common ways that you see coroplast signs, is hanging up with punctured holes in them. The owner of the sign will often puncture holes in the sign so that they can insert either a hook, grommet, or zip tie to hang it out.
  • A-frame signs are especially useful if you would like to display your sign on a sidewalk during business hours but take it down after closing. They also give you the possibility of changing out the image on a regular basis.
  • The classic yard sign is printed on corrugated plastic and then mounted to wire stakes, which are then lightly hammered into the ground.
