Vacuum packaging bags are composed of several different functional materials through thin film technology, and each layer of thin film plays a different role. Therefore, for our customers, it is quite difficult to choose the appropriate vacuum packaging bag. Today, we will carefully explain the performance of vacuum packaging bags and how to choose the appropriate packaging bag.
Vacuum packaging bags are also divided into transparent vacuum bags and aluminum foil vacuum bags. The composite material of vacuum packaging bags is usually PE and nylon, because nylon has good barrier performance, can effectively block moisture and gas, and can also maintain a vacuum state for a long time, making it the first choice of the public. Ordinary plastic bags are just ordinary plastic, and such plastic bags have pores on the surface and cannot be vacuum packaged, Even if it is reluctantly packaged, it is easy to experience air leakage over time, and even air leakage occurs immediately after packaging.
If you want to maintain the freshness of food for a long time, it cannot be achieved by vacuuming, because when the oxygen concentration in the packaging bag is ≤ 1%, the growth and reproduction speed of microorganisms will sharply decrease. When the oxygen concentration is ≤ 0.5%, most microorganisms will be inhibited and stop breeding. However, vacuum packaging cannot inhibit the reproduction of anaerobic bacteria and enzyme reactions, which can easily cause food spoilage and discoloration, Therefore, it is necessary to combine it with other auxiliary methods, such as refrigeration, rapid freezing, dehydration, high-temperature sterilization, irradiation sterilization, microwave sterilization, salt pickling, etc.
