Abstract

A slider resists erosion due to moisture, dirt and ultraviolet of sunlight and protects a pattern or the bonded surface from wear and tear. The slider contains a foam core, a top layer, a pattern, and a bottom layer. The foam core has a top surface, a bottom surface and edge surfaces. The top layer is a composite layer heat laminated to the top surface and edge surfaces of the foam core. The pattern is formed within the top layer and visible from outside of the top layer. The bottom layer is heat laminated to the bottom surface of the foam core.
