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 cellulose based substrate encapsulated with a polymeric film involves and an adhesive applied to at least one of the respective films. 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: A shipping container having an internal plastic bag is described, as is the method of forming the container. A flat container blank if first formed. This differs from a conventional blank only in that it has blind score lines centered vertically on each of the end panels. Adhesive strips are placed on or adjacent the major score lines separating the face and end panels of the container. Either a flat or gusseted bag is then laid on the blank with a sealed bottom edge adjacent the outside edges of the bottom flaps of the container. An open end of the bag extends beyond the upper edge of the container. The blank is then folded along the blind score lines to form a partially assembled container that can be shipped flat. Final assembly can be readily done in the field. The container eliminates the need for field insertion of the bag where one is required.
