摘要

A resealable closure (11) for packages (10) is provided which has a package integrity feature (34). The closure (11) includes a two-ply material having an inner film layer (12) and an outer film layer (13), forming a top of container (10). The outer film layer (13) has a sealing panel (26) completely covering a first panel (22) and a second panel (42) of the inner film layer (12). The sealing panel (26) is permanently attached to the first panel (22) and is releasably affixed a portion of the inner film layer around the perimeter of the first panel to form an opening in the top when the sealing panel with affixed first panel is peeled back from the top. The sealing panel is resealable against the top to seal the opening when the sealing panel is moved back against the top. The package integrity feature (34) comprises the second panel (36) of the inner layer which separates from the sealing panel to indicate that the container has been previously opened.
