Abstract: A cellulose based substrate (20) generally includes a cellulose based sheet having a corrugated medium (48) spanning between first and second linerboards (44 and 46), wherein the corrugated medium includes at least one sizing agent for moisture wicking resistance. The cellulose based substrate further includes a polymeric film (43) encapsulating at least a portion of the cellulose based sheet.

Abstract: A method for encapsulating a cellulose based substrate with polymeric films involves heating the respective films using a non-electrogmagnetic radiation heating source and providing a pressure differential between an environment defined between the films and an environment external to the films so that conformance of the film to the cellulose based substrate is promoted. The cellulose based substrate is entirely encapsulated by the films and the films are sealed around the peripheral edges of the container as well as edges that are defined adjacent slots and cutouts.

Abstract: A method for encapsulating a cellulose based substrate with polymeric film involves applying an adhesive to at least one of the respective films and providing a pressure differential between an environment defined between the films and an environment external to the films so that conformance of the films to the cellulose based substrate is promoted. The cellulose based substrate is encapsulated by the polymeric films and the films are sealed around the peripheral edges of the cellulose based substrate as well as edges that are defined by slots and cutouts.

Abstract: A method for encapsulating a cellulose based substrate with polymeric film involves raising the temperature of the respective films using an electromagnetic radiation source and providing a pressure differential between an environment defined between the films and an environment external to the films so that conformance of the films to the cellulose based substrates is promoted. The cellulose based substrate is entirely encapsulated by the plastic films and the films are sealed around the peripheral edges of the cellulose based substrate as well as edges that are defined by slots and cutouts.

Abstract: The present invention is directed to a convertible tray container and blank. In accordance with the present invention, a single sheet of foldable material is cut and scored to define container blank. The blank includes a plurality of substantially identical and separable units, each unit includes a bottom panel, a pair of first opposed side panels attached to the bottom panel and a pair of second opposed side panels attached to the bottom panel. Additionally, a corner flap is connected with each of the first opposed side panels. Further, a locking tab is connected with the corner flap. Still further a side panel slot formed in the second opposed side panels and a bottom stacking slot is form in the bottom panel.
