Abstract: A package includes a sheet of flexible material that has a first configuration of a generally flat configuration and a second configuration of a folded and sealed configuration. In the flat configuration, both prior to and after sealing, a user can utilize the sheet as a working surface. The flexible material includes a foldable portion and sealing areas disposed on first and second package portions on opposite sides of the foldable portion. When a sealed package is desired, a user can fold the sheet generally about the foldable portion so that the sealing areas generally align with one another. The user can then compress the aligned and abutting sealing areas to ensure sealing. To access the sealed contents, a user can simply pull the folded flexible material portions generally apart from one another to separate the engaged sealing areas.

Abstract: Hermetically sealed packages and hermetic seals based on oriented polymer films, such as oriented polyolefin polymers like biaxially oriented polypropylene (BOPP) and biaxially-oriented polyethylene terephthalatete (boPET). The films and seals are capable of providing high oxygen barrier properties effective for modified oxygen packaging.

Abstract: A reclosable food package for sliced food products to be maintained in a shingled arrangement and to provide convenient top access to the food product, the package including a rigid base member forming a compartment for receiving the food product and a rigid lid secured to the base. Advantageously, the base member includes a bottom wall and side wall portions that are configured to hold the food product in a shingled arrangement. The bottom wall further includes at least one channel that facilitates removal of the food product and cooperates to provide stability when the package is placed in an upright or horizontal position resting upon its bottom wall. The lid also has an inwardly extending annular bead which provides an audible sound when the lid is being placed upon the base.
