Launched two food anti-theft packaging

Japan’s Mitsubishi Gas Chemicals recently researched two successful anti-theft food packaging. One is the signal display technology. The package is green when it is intact, and it turns red once it is opened; the other is to put ferrous oxide in the package and install an oxygen indication graphic symbol in the transparent cover. Once opened, the oxygen-deficient atmosphere in the package is destroyed, ferrous oxide is converted to iron oxide, and the round mark changes color. This anti-theft package can be applied to granular, powdered, baked and canned foods.
