Abstract
A tamper-indicating label to be applied to a container. The label is longer than the circumference of the container, so that the label can be wrapped around the container and adhered to itself in an overlap area. The label includes a tamper-indicating mechanism in the overlap area irreversibly indicating if the label has been separated in the overlap area after initial application of the label to the container. The mechanism may be (1) an adhesive bond in the overlap area that is stronger than the label stock in the overlap area, (2) a line of weakening in the label, and/or (3) a frangible material, an adhesive, and/or printing that fractures and/or separates when the overlap area is opened.
