Abstract
A packaging tray formed of expanded polystyrene foam sheet material, having thick, curvilinearly interrupted perimeter edges. The edges are at least 10% thicker than the cross-sectional thickness of the major portions of the associated side walls of the tray. The perimeter edges are curvilinearly interrupted at at least two regular intervals along each side wall. The walls of the tray form corners which rise from the margins of the bottom panel of the tray at angles which can be greater than the angles at which the side walls rise from the bottom panel margins.
