Abstract: The present technology relates to tamper evident films, systems and methods for detecting tamper events in films or film packages. The present technology is especially useful in applications for detecting tamper events with individually packaged goods, as well as with bulk packaging or wrapped pallets in circumstances where visual inspection is hampered or prevented. 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 material can be separately wrapped and/or cowrapped in conjunction with a film.

Abstract: The present invention provides a monolayer film for use as label feedstock. The present film includes a blend of polyolefin polymer and an ethylene copolymer. In a preferred embodiment, the present film also includes an antiblocking agent.
