The tray, made from a single cardboard panel cut out and folded to form a base (1) and four raised sides (2 - 5), has tongues (14 - 17) cut out of the base and folded up against the side walls to form aeration holes (12, 13), spacers for stacking trays on top of one another, or side wall reinforcing elements. The tongues are positioned so that they reinforce the corners of the box.
