A bodyboard with skins covering the top and bottom surfaces of a foam plank that forms a core in the bodyboard. The top skin is prepared by heat-expanding a foamable matrix layer having a polyolefin film deposited on the top surface of the matrix layer. With the application of heat, the matrix layer becomes a foam, and the polyolefin film softens and integrates with the foam. Graphics carried internally on the film become an integral part of the foam. |
