Patent 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.
