A resealable closure for a container in which package integrity is indicated by a structure which breaks and/or produces an audible sound when the resealable closure is opened for a first time. The package integrity feature, in one form includes at least one strip initially affixed to two portions which comprise the resealable closure so that upon opening the resealable closure for a first time, at least one of the strips breaks, thereby producing the audible sound. The strips may include a weakened portion such as a narrowing. Integrity of the package is indicated by an intact strip viewable upon opening the resealable closure and conversely, a broken or non-intact strip would indicate that the resealable closure has been previously opened. Package integrity may also be shown by a movable second panel or movable die cut tab portions.

A package having a package integrity closure comprising: a top, a flap formed in the top, when the flap is disengaged from a remainder of the top an access opening is exposed in the top;a sealing panel, which covers the flap and the access opening, sealingly engages the top around the access opening so as to originally seal the package and then, after having been opened a first time, be resealable against the top; andat least two strips formed in the top having portions extending from the remainder of the top and the flap, and upon initial opening of the package, each of the at least two strips breaks such that the portions affixed to the remainder of the top and the flap respectively are separated, thereby providing an audible sound indication that the package ahs been opened;wherein each of the two strips has a weakened portion where the strip breaks weakened portions are disposed in two different locations from an end of the container such that the two strips break at different times upon opening the resealable closure to thereby produce two separate audible sounds upon opening the resealable closure. 14. The package of claim 13, further comprising three strips, wherein spacing between the strips, prior to breaking of any of them, is small enough such that items in the container cannot be removed from the container between the strips without breaking at least one of the plurality of strips. 15. The package of claim 13, wherein the strip comprises a weakened portion, whereby the strip breaks prior to opening the package significantly enough to be able to remove an item contained therein. 16. The package of claim 13, wherein said sealing panel comprises a see-through window portion lying over one of the two strips prior to the resealable closure being opened for a first time. 17. A package integrity indicating closure, the closure comprising: a film layer forming a top of a container and having a flap defining an access opening to gain access to the contents of the container, and having at least one strip formed of a top of the container joining the flap to a remaining portion of the top;a sealing panel completely covering the flap of the film layer; andreleasable adhesive provided on either or both the sealing panel or on the film layer for adhering 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,wherein upon peeling the sealing panel back for a first time, the at least one strip joining the flap to the remaining portion of the top breaks into a plurality of portions. 18.
