Japanese food packaging experts have developed an anti-tamper food 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.
This anti-theft food packaging technology is:
Place a small bag of ferrous oxide in the packaging container and another oxygen indicator circle mark 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. This foodstuff-resistant food packaging technology can be applied to granular, powdered, bakery and canned food packaging.
