ABSTRACT:
An octagonal tray and one-piece blank for forming it. The tray is formed from corrugated paperboard and is provided on at least its interior bottom and wall surfaces with a wax coating. The tray includes vertically disposed posts at its end walls, the posts increasing the vertical stacking strength of the tray and also reducing the requirement that the trays be accurately vertically aligned when stacked one on top of the other. The tray is manually erected by folding along hinge or fold axes formed in the blank. Crushed ice is placed among and on fish or poultry within the tray for example, with the tray then being lidded for shipment.
