    Abstract: Corrugated paper includes first and second sheets of paper; and a layer of structured paper disposed between the first and second sheets of paper. The layer of structured paper includes cells, in which at least some of the cells are negative Poisson's ratio (NPR) cells. Each NPR cell includes top and bottom walls, and side walls angled inwards toward a central portion of the NPR cell, such that application of a compressive force between the top and bottom walls of the NPR cell causes a lateral dimension of the NPR cell between opposite side walls to decrease. The NPR cells exhibit a Poisson's ratio of between 0 and −1.
