Abstract: A casket shell made of a corrugated paperboard. The shell is made of a triple-ply inner layer and a single-ply outer layer laminated over the inner layer. The corrugation in the side members of both layers are aligned vertically for maximum vertical tensile strength. The corrugation in the vertical corners in the inner layer are oriented horizontally for maximum stiffness and shape retention properties. The casket shell has a uniform thickness throughout the sides, ends and bottom thereof, and square corners to simulate the appearance of a wood structure. Each end has a vertical median slot therein for inserting the edges of a decorative covering fabric material. Both sides are prestressed to maintain a straight alignment.
