Posters Paper Recycling Laminated or Mounted Posters Are Not Recyclable A poster can’t be recycled if it has been laminated or mounted. Laminated posters have a shiny, plastic coating on both sides. Mounted posters are on a board to provide them with more rigid support. Remove Blu-Tack and Other Adhesives First Before recycling a poster, be sure to remove Blu-tack or any other adhesives first.
