A resealable closure for a container in which package integrity is indicated by a structure which connects the closure to a remaining portion of the container which must be broken in order to gain access to the contents of the container for a first time. The package integrity feature, in one form, includes a structure associated with the closure, wherein upon opening the closure for a first time, the structure stretches, increasing a length of the structure until the structure eventually breaks, leaving one or both residual ends of the broken structure rippled or curved upward from the remainder of the container. In one alternative form, the structure is associated with a pull tab of the sealing panel, which comprises the closure, whereby either the structure must be broken first, prior to pulling back the sealing panel, or while pulling back the sealing panel for a first time, the structure breaks, prior to gaining access to the contents therein. Advantageously, the package integrity feature is integrally formed with the closure and a remaining portion of the container. Integrity of the package is indicated by visually observing an intact breakable structure.
