Japanese Food Anti-Theft Packing Advent

March 07, 2019

Japanese food experts have developed a food tamper-proof packaging technology. With this technique, as soon as the lid of the food container is opened, the round mark on the transparent lid changes color.

It is reported that this food anti-tamper packaging technology is to put a small bag of ferrous oxide into the packaging container, and another oxygen indicator circle mark is installed on the transparent bottle cap. Once the bottle cap is opened, the oxygen-deficient atmosphere inside the container is destroyed, and the ferrous oxide is converted into iron oxide, and the color of the round mark also changes. It is said that this food anti-tamper packaging technology can be applied to granular, powdered, baked and canned foods.
