More specifically, an image-laden material with a desired imprinted image and which is made of an image-laden capable polyethylene film, adhesive, and a polyvinyl chloride (PVC) protection layer is provided to a PE mold to form a shape similarly to the desired shape of the thermoplastic material. The shaped image-laden material is then transferred to a second PU mold for forming the desired image-laden shape of a biodegradable polyurethane foam material where polyurethane foam is premixed with a biodegradable agent to initiate a foaming process and added to the mold. During the foaming process the polyurethane foam material increases in mass while forming an outer adhesive surface that forms a strong cohesion with the polyethylene film of the image-laden material.
