A slider resists corrosion of moisture, dirt and ultraviolet of sunlight and prevents patterns therein from wear and tear; furthermore, the slider also provides a smooth touching feeling to users. The slider mainly contains a polyethylene foaming board, an upper polyethylene foaming skin, a first plastic film, a lower polyethyle ne foaming skin and a second plastic film. The polyethylene foaming board has a top surface, a bottom surface and edge surfaces. The upper polyethylene foaming skin contai ns an inner surface and an outer surface. The inner surface of the upper polyethylene foaming skin is bonded with the top surface and the edge surfaces of the polyethylene foaming board. The first plastic film is bonded with the outer surface of th e upper polyethylene foaming skin. The lower polyethylene foaming skin contains an inner surface and an outer surface. The inner surface of the lower polyethylene foaming skin is bonded with the bottom surface of the polyethylene foaming board. Th e second plastic film is bonded with the outer surface of the lower polyethyle ne foaming skin. The upper and the lower polyethylene foaming skins have foamin g rates less than a foaming rate of the polyethylene foaming board.
