What are the Advantages of Vacuum bags?

Vacuum packaging bag refers to a packaging method in which the product is added to an airtight packaging container, the air inside the container is removed, and the sealed container reaches a predetermined degree of vacuum.

The main function of the vacuum bag is to remove oxygen to help prevent food spoilage. The principle is also relatively simple, because the mildew and spoilage of food is mainly caused by the activities of microorganisms, and the survival of most microorganisms (such as mold and yeast) requires oxygen. , and vacuum bag uses this principle to pump out the oxygen in the packaging bag and food cells, so that the micro-materials lose the “survival environment”.
