U.S. Develops New Plastic Film

U.S. researchers put a plastic film containing a chemical called AIn090rb in the food packaging bag to remove oxygen from the package so that the packaged food can not deteriorate for a long time. The chemical substance is in a dormant state until it is irradiated with special light waves. Chemical effects begin to appear when exposed to special light waves. This means that in the packaging of foods, there is no need for complicated deoxygenation treatment, as long as it is irradiated with special light waves in the final process of food packaging. Russian experts have added dehydrated acids, various mineral salts and enzymes to polymers in packaging materials. The surface of the packaging bag rich in these substances can absorb excess moisture in the packaged food and kill bacteria, thereby improving the internal environment of the packaging bag. At the same time, the enzymes in the additive can also regulate the odor of the food and create a living space for nutrients in the food.
