Unitary preform includes a knocked-down flat shroud (20) having sidewalls received inside a knocked-down flat tray (21) and adhered thereto by means of a releasable adhesive for handling by a conventional case packer having a single magazine. The shroud is releasable when the case is packed to provide a display tray for product packed therein. Alternatively, the tray may be received inside the shroud with the handles being part of the shroud. Methods of manufacture include steps of folding and adhering separately formed flat parts, or folding a unitary blank having a shroud blank and a tray blank connected by webs.
