A disposable paperboard tray for retaining lading during transport and storage with a number of loaded trays stacked one on top of the other. The floor or bottom wall of the tray has a plurality of punched, spaced apart score lines or perforations which are not cut entirely through the floor whereby to provide a selective arrangement of protuberances on the bottom outside surface of the floor. When a plurality of trays carrying lading, such as conventional canned foods, are stacked one on top of the other, the protuberances engage the upper ends of the cans stacked in a nether tray to prevent one tray from sliding or inadvertently slipping one relative to its neighbor.
