Abstract
A corrugated plastic sheet is provided having two outer sheets and internal ribs. The ratio of the thicknesses between each outer sheet and a rib is approximately 2:1. This ratio can be adjusted so that the upper and lower sheets are thicker than the thickness of the ribs. The die itself does not need to be changed. Rather, the die settings are merely adjusted.
