ABSTRACT:
A composite tray is formed from top and bottom press formed tray members. The top tray member includes a base and sidewalls, and a plurality of embossments or raised surfaces are formed on the base thereof, while the bottom tray member also includes a base and sidewalls, with a plurality of debossments formed on the base thereof. The bottom tray member is of slightly larger dimensions than the top tray member such that the top tray member may be fitted within the bottom tray member and affixed thereto. The opposed bases of the top and bottom trays cooperate to inhibit unwanted twisting or flexing of the composite tray, thereby enhancing the structural rigidity of the tray. In a preferred embodiment of the subject invention, the bases in the top and bottom tray members are disposed in mirror image relationship to further rigidify the composite tray. Polymer coatings may be provided on the exposed surfaces of the composite tray to provide a moisture-liquid barrier. Methods of making the embodiments of the composite tray are also disclosed.
