Vacuum packaging bags are mainly divided into transparent vacuum bags and aluminum foil vacuum bags. Generally, the composite material of vacuum bags is PE and nylon. They are composed of several plastic films with different functions that are skillfully combined together, and each layer of film has a different function. Nylon has excellent barrier function, which can effectively block moisture and air, maintaining a durable vacuum state. However, general plastic bags are only made of ethylene as the monomer, and these bags have air holes on the surface that cannot be vacuum treated. Even if the plastic bags are forcibly vacuum packed, over time, they will leak and some problems will occur.
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 less than 1%, the growth and reproduction speed of microorganisms quickly decrease. When the oxygen concentration is less than 0.5%, the vast majority of bacteria will be suppressed and continue to reproduce, but under vacuum conditions, anaerobic bacteria cannot be suppressed, as well as food degradation and oxidation caused by enzyme reactions. Therefore, it needs to be allocated in conjunction with other auxiliary methods. For example, methods such as refrigeration, rapid freezing, dehydration, high-temperature sterilization, microwave sterilization, salt pickling, etc. By mastering these methods, one can correctly use vacuum packaging bags.
