ABSTRACT:
A one-piece corrugated tray is formed of a blank of sheet material wherein a filler is sandwiched between an lower liner and an upper liner. The blank is slit scored transversely to define end panels, end walls, dividing walls, and floor panels between successive walls. The blank is then power rolled so that the blank is folded up ninety degrees at front slit scores and folded down one-hundred-eighty degrees at front slit scores. The resulting tray has double-thickness walls and double-thickness floors. Trays of this construction can be used for handling and shipping decorative automotive body panels and other items of manufacture that must be protected from rubbing one another or lapping over one another.
