The tray is covered by a separate sleeve that extends across the top of the tray and down opposed sides and across the bottom of the tray. The trays may be stacked with an upper tray resting on the shoulders of the lower tray. The sleeve is a sleeve for the stack of trays with the side panels of the sleeve sized for different numbers of trays in the stack. There may be frictional tabs in the side panels of the tray or trays which have frictional engagement with the side panels of the sleeve.
