Abstract
A returnable packaging system provides product protection in a simplified, low cost design. The packaging system includes a conventional pallet structure having an upper surface covered by a protective sheet. A plurality of parts are layered between a plurality of trays, the trays being identical to one another. The trays preferably generally are planar, being constructed from relatively thin sheets having receptacles formed on opposed sides of the sheets. The receptacles have a silhouette designed to receive a portion of the parts carried by the trays. The bottom tray of a second part layer serves as the cover for a first part layer so that an interlocked structure results which prevents horizontal movement of the individual parts. The layered assembly is encapsulated in a heat shrinkable cover. When shrunk, the cover holds the entire system in a stable integral package condition. The cover is removed when the parts are used.
