Abstract: A tamper indicating, resealable closure for a package includes first and second film layers releasably adhesively joined together such that the first and second film layers are at least partially separable when the second film layer is pulled away from the first film layer. The first film layer includes first and second tear lines formed thereon to define first and second panel sections respectively. The first panel section defines an access opening through the first film layer when it is separated along the first tear line during an initial separation of the first and second film layers. The second panel section also becomes separated from the first film layer when the second film layer is separated from the first film layer to provide an indication of an initial opening of the closure. Subsequently, the second film layer may be re-adhered to the first film layer to reseal the access opening, while the second panel section remains separated from the first film layer.

Abstract: The present invention relates to a flexible magnetic wafer seal for adhesive attachment to folded pieces, such as brochures, folded cards, self-mailers and postal mailers, which are generally made of card stock. One or more flexible magnetic wafer seals may be adhesively attached to the open edges of a folded piece to secure the open edges together, for example, as required during the mailing process. The magnetic wafer seal can then be broken, preferably along at least one line of weakness, allowing the piece to be unfolded and converting the magnetic wafer seal into at least two magnetic holders for securing a piece to a metal surface. The unfolded piece can then be secured to a metallic surface by placing the side of the piece with the magnetic holders against the metallic surface, thereby allowing the magnetic holders to engage the metal surface, holding the piece in place.
