ABSTRACT:
An expandable sealed container is formed of first and second panels, each formed of at least first and second sheets. The first sheet of each of the panels is formed of a polyvinyl fluoride film and the second sheet is formed of a flexible vinyl. In one embodiment, one surface of the polyvinyl fluoride film is treated to receive an adhesive to adhesively join the polyvinyl fluoride sheet to the vinyl sheet. The opposed second surface is capable of receiving a heat seam to form a complete peripheral seal about the container. In one configuration, the polyvinyl fluoride film sheets of each pair of sheets are facing each other and receive the heat seam. Alternately, the vinyl layers are disposed innermost to receive the heat seam. Further, a polyvinyl fluoride film having both surfaces treated to receive an adhesive is adhesively joined to the outermost surface of the vinyl sheet. The heat seam is formed about the periphery of the vinyl sheets.
