Abstract: A formed article includes a rigid film, a liner film, and a cavity. The rigid film includes a thickness and a line of weakness. The rigid film and the liner film are joined to each other. Further, the line of weakness is positioned in the cavity. The formed article is configured to facilitate separation (e.g., peeling) of the rigid film from the liner film.

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.
