Abstract:

A resealable label flap for use with a product package including a tamper indicating tab that remains in contact with the package body to indicate that the label flap has been removed from the package body. The tamper indicating tab includes a first ink layer that defines an indicia or pattern on the top surface of the tamper indicating tab. A second ink layer is applied over the entire top surface of the tamper indicating tab, including over the first ink layer. The second ink layer does not bond to the first ink layer. When the label flap is initially pulled from the product package, the tamper indicating tab separates from the remaining portions of the label flap. As the tamper indicating tab separates from the label flap, the first ink layer and the second ink layer separate from each other such that the portions of the second ink layer applied over the first ink layer remain in contact with the top layer of the label flap. The separation of the first ink layer and the second ink layer during the initial removal of the label flap indicates to a user that the label flap has been opened.
