Abstract:
A laminated structure comprising:a core material having a first surface and including a foamed polyolefin having a density of between 12 and 59 pounds per cubic foot; anda first polymer foam layer laminated to the first surface, wherein the first polymer foam layer has an outer surface which is an outer surface of the laminated structure,the core material and the first polymer foam layer each includes a polyethylene andthe first polymer foam layer being characterized by:(a) an average foam density between about 2 and 10 pounds per cubic foot and which is less than the density of the core material; and(b) a compression resistance (at 25%) which is less than the compression resistance (at 25%) of the core material.
