Abstract
A `high density` corrugated wafer board panel is provided. The wafer board panel has a substantially uniform density ranging from between about 700 kg/m.sup.3 to 900 kg/m.sup.3. As a result of increasing the density of the panel without changing the panel weight per projected unit area, a panel having improved overall flexure performance properties is provided.
