Abstract
A sports board comprises a foam core with a top surface, a bottom surface and edge surfaces. A top layer is heat laminated to the top surface and edge surfaces of the foam core. The top layer has a first plastic film having a top surface and a bottom surface. A first adhesive resin film has a top surface and a bottom surface. The top surface is heat laminated to the bottom surface of the first plastic film and the bottom surface heat laminated to the top surface and edge surfaces of the foam core. A bottom layer is heat laminated to the bottom surface of the foam core.
