Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
