Abstract
A sheet structure includes a pair of corrugated sheets formed in a zigzag pattern, the pair comprising an upper sheet and a lower sheet. In an exemplary embodiment, each of the pair of corrugated sheets further includes a flat portion disposed at selected intervals between individual zigzags. The flat portions of the upper sheet are aligned with corresponding flat portions of the lower sheet so as to maintain the upper and lower sheets in a double wall configuration.
