Vacuum foil aluminum bags are becoming more and more widely used, so what is the use of them? It is to reduce the oxygen content in the package, so as to avoid mildew and deterioration of the packaged food, maintain the color and fragrance of the food, and prolong the shelf life.
 

The function of the vacuum foil aluminum bags is mainly to deoxygenate, so as to prevent food from spoiling. The principle is relatively simple. Because the mildew and spoilage of food is mainly caused by the activity of microorganisms, and most microorganisms need oxygen to survive, and this product is Using this principle, the oxygen in the cells of the food in the bag is pumped out, so that the microorganisms lose the living environment, and most microorganisms are controlled and stop reproducing.

Another important function of vacuum foil aluminum bags is the oxidation of Fangzi food. Because oily food contains a lot of unsaturated fatty acids, it is oxidized by the action of oxygen, which makes the food taste bad and spoiled. The unstable substances in the pigment are subjected to the action of oxygen, which darkens the color. Therefore, deoxygenation can prevent food from spoiling and maintain its color, aroma, taste and nutritional value.
