Abstract
Impact indicators which include an impact registering structure are provided for a package. The impact registering structure registers a location and an elapsed time of an impact of excessive force on the package. The structure includes a first region, a second region, and a barrier film. The first region contains a first element, and the second region contains a second element. The first and second elements are selected to register the location and the elapsed time of the impact when coming in contact. The barrier film separates the first and second regions, and is calibrated to rupture with a specified impact force. Once ruptured, the first element and the second element contact, in part, to provide a location indication of the rupture in the barrier film and a time elapsed indication indicative of the elapsed time from the rupture in the barrier film.
