The invention relates to foam 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 foams that include a core of a low density foam and one or more skins of relatively high density foam covering the core. The skins 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 while modestly increasing the weight of the laminated structure, for example. Uses of the foam structures include, but are not limited to, packaging materials, gym mats, body boards, or eaves fillers. The skin can act as a hinge to fold a die cut piece into a collapsible packaging system.

[ What is claimed is:] [1.] A laminated foam structure comprising a first article laminated to a first surface of a second foam article, wherein the first article is a first foam article having an average foam density that is at least 1.5 times greater than the average foam density of the second foam article and a volume that is at least 1.5 times smaller than the volume of the second foam article, wherein the first foam article, which is a skin, is laminated to a surface of the second foam article, which is a core, the core comprising at least two core elements separated by a bending region that is a gap or crease in the core, whereby the laminated foam structure can be folded along the bending region.
