The Russian Institute of Applied Biotechnology has developed a plastic bag that can absorb water, sterilize, and can be reused many times. Foods that are easily degraded, such as cheese sausage, can be stored for a long time. Russian experts have added dehydrated mineral salts and enzymes to plastic polymers. The inner surface of the plastic bag, which is rich in these substances, can absorb excess moisture and kill bacteria, thereby improving the internal environment of the packaging bag.
The enzyme in the additive also regulates the odor of the food, creating a bottom-up space for nutrients in the food. This new type of plastic bag can be used repeatedly and can be used repeatedly 9 times under specific conditions.
