ABSTRACT:
A polymeric foam article has at least two thermoplastic polymer foams in layered orientation, each of the thermoplastic polymer foams having an adjoining surface that contains a polymer skin, a thickness dimension perpendicular to the adjoining surface, perforations that are less than one millimeter in diameter that penetrate through the adjoining surface to a depth less than the thickness dimension of the foam, where the adjoining surface of one thermoplastic polymer foam is adjacent and adhered to the adjoining surface of another thermoplastic polymer foam with an adhesive thereby affixing the thermoplastic polymer foams to one another.
