Patent ID: 8075989

Claim:
A polymeric foam article comprising at least two thermoplastic polymer foams in layered orientation, each of the thermoplastic polymer foams having: (a) an adjoining surface that contains a polymer skin; (b) a thickness dimension perpendicular to the adjoining surface; (c) perforations that have a diameter of 0.5 millimeters or more and one millimeter or less and that penetrate through the adjoining surface to a depth less than the thickness dimension of the foam; wherein 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 and wherein the total perforation area is at least 2.80 square millimeters per square centimeter of adjoining surface and the perforated surface area is 50% or less of the planar surface area of the perforated surface, wherein the perforated foam has a higher tensile strength than the foam having no perforations.
