The vacuum packaging bag is composed of several materials with different functions through the film process. Each layer of film plays a different role. Therefore, it is difficult for our customers to choose a suitable vacuum packaging bag. So today we will explain to you the performance of vacuum packaging bags
in detail and how to choose a suitable packaging bag. Vacuum packaging bags are further divided into transparent vacuum bags and aluminum foil vacuum bags. The composite material of vacuum packaging bags is usually a composite of PE and nylon, because nylon has good barrier properties, which can effectively block moisture and gas, and can also maintain vacuum for a long time. It has become the first choice of the public, and ordinary plastic bags are just ordinary plastics. Such plastic bags have pores on the surface and cannot be vacuum-packed. Even if they are barely packed, they are prone to air leakage problems after a long time, and even It leaked as soon as it was packaged. If you want to maintain the freshness of food for a long time, it is not possible to achieve it by vacuuming, because when the oxygen concentration in the packaging bag≤1%, the growth and reproduction rate of microorganisms will drop sharply, and the oxygen concentration≤At 0.5%, most microorganisms will be inhibited and stop multiplying, and vacuum packaging cannot inhibit the reproduction and enzymatic reaction of anaerobic bacteria, so it is easy to cause food deterioration and discoloration, so it needs to be combined with other auxiliary methods, such as refrigeration, Quick freezing, dehydration, high temperature sterilization, irradiation sterilization, microwave sterilization, salt pickling, etc.
