Abstract
A slider includes a foam board, a top layer and a bottom layer. The foam board is a polystyrene foam board that is easily formed and molded. Furthermore, a bottom of the foam board has a rail portion protruded with a plurality of foam rails therefrom and the foam rails are parallel with each other. In addition, the top layer and the bottom layer are made of polyethylene materials and comprise interface coatings respectively, so that the top layer and the bottom layer made of polyethylene could heat bonded to the polystyrene foam board without adhesives by the first and second interface coatings.
