The air is rare and the low oxygen effect is achieved, so that the microorganisms have no living conditions to achieve fresh fruit and no disease. The purpose of the occurrence. Applications include vacuum packaging in plastic bags, aluminum foil packaging, and glassware packaging. Packaging materials can be selected according to the type of item. Since the fruit is a fresh food, it is still undergoing respiration, and high oxygen deficiency can cause physiological diseases. Therefore, the fruit is less vacuum-packed.
