A resealable package integrity closure includes a film layer forming a top of container and having a flap defining an access opening to gain access to the contents of the container. A sealing panel completely covers the flap of the film layer. A releasable adhesive is provided on either or both the film layer and the sealing panel for adhering the sealing panel to the film layer. The sealing panel is releasable from the film layer by pulling the sealing panel back in a peeling direction and reclosable against the top to seal the access opening when the sealing panel is moved back against the top. A coating of transferable material is provided on either the sealing panel or on the film layer, which is transferable therebetween, respectively, when the sealing panel is pulled back from the film layer for a first time to provide a visual indication that the closure has been previously opened.

A package integrity indicating closure, the closure comprising: a film layer forming the top of a container and having a flap defining an access opening to gain access to the contents of the container;a sealing panel completely covering the flap of the film layer, the sealing panel and the flap being permanently adhered to one another to thereby form the access opening, a margin of the sealing panel includes a portion of the sealing panel extending beyond the access opening;releasable adhesive provided on either the margin of the sealing panel facing the film layer or on the film layer facing the margin the releasable adhesive configured to adhere the sealing panel to the film layer, the sealing panel being releasable from the film layer by pulling the sealing panel back in a peeling direction and reclosable against the top to seal the access opening when the sealing panel is moved back against the top;a coating of transferable material on either the margin of the sealing panel on a first surface thereof facing the film layer or on the film layer on a second surface thereof facing the margin of the sealing panel, the coating being adhered near a perimeter of the first or second surfaces so that an inner area has the releasable adhesive and an outer area concentric with the inner area has at least the coating; andwherein the coating is transferable from the sealing panel to the film layer or the film layer to the sealing panel to thereby provide a visual indication that the closure has been previously opened, the visual indication being at least a portion of the coating that is visually exposed beyond the sealing panel upon misalignment in reclosing the sealing panel on the film layer. 14. The package integrity indicating closure of claim 13, wherein a bond strength between the releasable adhesive and the coating is stronger than a bond strength between the coating and the film layer. 15.
