<p>An expanded laminate material includes a plastic sheet and two expanded layers. The plastic sheet has upper and lower surfaces and a thickness of between 0.05 and 1 mm. The first expanded layer has upper and lower surfaces, a foam density of between about 1.2 and 8 pcf and a thickness of between about 1 and 8 mm. The lower surface of the first expanded layer is directly bonded to the upper surface of the plastic sheet. The a second expanded layer has upper and lower surfaces, a foam density of between about 1.2 and 8 pcf and a thickness of between about 1 and 8 mm. The upper surface of the second expanded layer is directly bonded to the lower surface of the plastic sheet. The first and second expanded layers comprise a material selected from the group consisting of expanded polyethylene and expanded polypropylene.</p> |
