ABSTRACT:
A tray providing better bottom strength and better stacking strength. The tray has a double-ply base panel which will not bulge to the extent a single-ply tray would. Double-ply lower end panels are attached to the double-ply base panel. These lower end panels in conjunction with the upper end panels, the side end flaps and the interior locking panels provide quintuple-ply end sections which provide better strength.
