The invention relates to layered structures with enhanced physical properties, which can be used in the areas of packaging, athletics, water sports, and construction. In general, the structures are laminated polymer articles that include a layer of a low density foam and one or more layers of relatively high density material. The high density layers provide improved physical properties to the foam structures, by improving the flexural strength, resistance to bending, and resulting damage from bending in the laminated foam structure and/or having a region that expands, while the high density material, for example, modestly increases the weight of the laminated structure. Uses of the foam structures include, but are not limited to, packaging materials, gym mats, body boards, or eaves fillers. The high density material can act as a hinge and/or expansion joint or region to fold a die cut piece into a collapsible packaging system.
