ABSTRACT:
A multilayer innerseal having a grip tab extending across the innerseal. Force applied to the grip tab is concentrated at the base of the grip tab and promotes a complete failure of the innerseal. In use, a substantial portion of the original innerseal remains adhered to the container to providing evidence of tampering and to frustrate efforts to reseal the container.
