A stackable tray is formed from a single blank of cut and scored corrugated paperboard or the like with a substantially rectangular bottom panel, cut away side walls reinforced with extra panels that extend over the bottom panel and reinforced end panels that are adhered to the end walls. The reinforced end panels include score lines on alternative sides of the blank which automatically produce integral corner posts for the tray when the panels are folded and adhered to the end walls. The reinforcing panels for the end walls also include locking tabs which cooperate with locking slots in the tray bottom panels when a series of trays are stacked one upon the other.
