The invention is directed towards a film-based polymeric cellular matrix, methods for making the polymeric cellular matrix, articles of manufacture incorporating the polymeric matrix and methods for making articles of manufacture. The polymeric cellular matrix is characterized as a plurality of generally identical cells (open-ended geometric prisms) arranged to form a repeating geometric form. The matrix is particularly suited for use as a core between two panels.

What is claimed: 1. A collapsible polymeric matrix of single-walled cells comprising: a first row of film-based, open-ended hollow prisms, each prism having a perimeter enclosing wall that includes a plurality of wall segments, the first row having at least a first type of prism alternating with a second type of prism to form a repeating sequence of prisms wherein each prism in the row shares a common enclosing wall segment with a directly adjacent prism; and a second row of film-based, open-ended hollow prisms, each prism having a perimeter enclosing wall that includes a plurality of wall segments, the second row having at least the first type of prism alternating with the second type of prism to form a repeating sequence of prisms, wherein each prism in the row shares a common enclosing wall segment with a directly adjacent prism, wherein each row has a generally constant upper and lower boundary and wherein no row overlaps another row, when the matrix is in an expanded state, wherein each wall segment of each prism defines an orifice to establish fluid communication with an adjacent prism. 2. The matrix of claim 1 wherein the matrix is registered. 3. The matrix of claim 1 wherein the matrix is non-registered. 4. The matrix of claim 1 wherein the perimeter enclosing wall of each row of open-ended prisms comprises a first edge and a second edge, and wherein the matrix further comprises a flexible panel having a first major surface and a second major surface, the first major surface being substantially bonded to the first edges, thereby establishing an additional wall for substantially each prism to which the panel is bonded. 5. The matrix of claim 4 further comprising a second flexible panel having a first major surface and a second major surface, the first major surface of the second flexible panel being substantially bonded to the second edges, thereby establishing an additional wall for substantially each prism to which the second panel is bonded. 6. The matrix of claim 5 wherein the first and second flexible panels include perimeter portions and wherein the perimeter portions are sealingly joined to each other in opposition, thereby creating a fluid impervious envelope wholly surrounding the cellular matrix, and further comprising a valve for permitting fluid ingress and egress between the environment and the matrix. 7. The matrix of claim 6 wherein the resulting article is one of a fluid inflatable mattress, a fluid inflatable vest, a fluid inflatable personal hydration container, or a fluid inflatable seat cushion. 8. The matrix of claim 1 further comprising a biocide integrated there into. 9. The matrix of claim 1 wherein the perimeter enclosing wall of each row of open-ended prisms comprises a first edge and a second edge, and wherein each edge further comprises a component having a lower melting point than the portion of the wall between the edges. 10. The matrix of claim 7 further comprising a biocide integrated into the matrix. 11. The matrix of claim 7 wherein the perimeter enclosing wall of each row of open-ended prisms comprises a first edge and a second edge, and wherein each edge further comprises a component having a lower melting point than the portion of the wall between the edges. 12. A collapsible polymeric matrix of single-walled cells comprising: a first row of film-based, open-ended hollow prisms, each prism having a perimeter enclosing wall that includes a plurality of wall segments, the first row having at least a first type of prism alternating with a second type of prism to form a repeating sequence of prisms wherein each prism in the row shares a common enclosing wall segment with a directly adjacent prism; and a second row of film-based, open-ended hollow prisms, each prism having a perimeter enclosing wall that includes a plurality of wall segments, the second row having at least the first type of prism alternating with the second type of prism to form a repeating sequence of prisms, wherein each prism in the row shares a common enclosing wall segment with a directly adjacent prism, wherein each row has a generally constant upper and lower boundary, wherein no row overlaps another row, when the matrix is in an expanded state, and wherein at least one wall of each prism defines an orifice to establish fluid communication with an adjacent prism. 13. The matrix of claim 12 wherein the matrix is registered. 14. The matrix of claim 12 wherein the matrix is non-registered. 15. The matrix of claim 12 wherein the perimeter enclosing wall of each row of open-ended prisms comprises a first edge and a second edge, and wherein the matrix further comprises a flexible panel having a first major surface and a second major surface, the first major surface being substantially bonded to the first edges, thereby establishing an additional wall for substantially each prism to which the panel is bonded. 16. The matrix of claim 15 further comprising a second flexible panel having a first major surface and a second major surface, the first major surface of the second flexible panel being substantially bonded to the second edges, thereby establishing an additional wall for substantially each prism to which the second panel is bonded. 17. The matrix of claim 16 wherein the first and second flexible panels include perimeter portions and wherein the perimeter portions are sealingly joined to each other in opposition, thereby creating a fluid impervious envelope wholly surrounding the cellular matrix, and further comprising a valve for permitting fluid ingress and egress between the environment and the matrix. 18. The matrix of claim 12 wherein the resulting article is one of a fluid inflatable mattress, a fluid inflatable vest, a fluid inflatable personal hydration container, or a fluid inflatable seat cushion. 19. The matrix of claim 18 further comprising a biocide integrated into the matrix. 20. The matrix of claim 12 wherein the perimeter enclosing wall of each row of open-ended prisms comprises a first edge and a second edge, and wherein each edge further comprises a component having a lower melting point than the portion of the wall between the edges. 21. The matrix of claim 18 wherein the perimeter enclosing wall of each row of open-ended prisms comprises a first edge and a second edge, and wherein each edge further comprises a component having a lower melting point than the portion of the wall between the edges.
