Abstract: Packaging for an object such as a digital recording medium that is contained within a plastic molded tray that is mounted on a panel. The tray is molded with extensions from opposite edges of one surface of the tray. Each extension folds to form a peripheral wall along that edge and it engages an element of the tray to permanently lock the extension in place. In their locked positions, the extensions fold around opposite edges of the panel so that the panel is locked in place under the tray.
