Abstract: A package in the form of a tray, carton or case has at least a base, side walls and end walls, a support formed by two panels positioned within the package, one adjacent each of end walls, or side walls, protrusions, and/or recesses on each panel of a size so that with the packages positioned in a stack, vertically adjacent protrusions and/or recesses are in contact without substantial compression of the packaging material positioned between vertically adjacent panels, and positioned apertures in the package to receive protrusions. The package in a preferred form also includes lugs provided at each corner of one face, the lugs being angled and the package also having corresponding cut-outs so that in a vertical stack the lugs of one package are positioned in the cut-outs of a vertically adjacent package.
