TAMPER EVENT DETECTION FILMS, SYSTEMS AND METHODS

摘要

The present technology relates to tamper evident films, systems and methods for detecting tamper events in films or film packages. In one or more preferred systems, films and methods of the present technology utilize a conductive pattern, a sensor and/or alarm circuit, and a wrapping film, such as a stretch film, shrink wrap, bagging or stretchhooder In at least one particularly preferred embodiment, films of the present technology are stretch films having conductive ink patterns applied thereto that remain conductive when the films are stretched to a percent stretch of about 1 % or greater In other embodiments, a conductive matenal can be separately wrapped and/or cowrapped in conjunction with a film Preferred tamper detection systems of the present technology also utilize radio frequency identification technology to indicate whether a tamper event has occurred
