Vacuum bags have transparent vacuum bags and aluminum foil vacuum bags. Material is a composite of PE and nylon. Nylon has good barrier properties, can block moisture and gas,maintain for a long time.
If you want to maintain the freshness of food for a long time, can't just be achieved by vacuuming, because when the oxygen concentration is ≤1%, the growth and reproduction speed of microorganisms will drop sharply, when the oxygen concentration is ≤ 0.5%, the maximum Most microorganisms will be inhibited and stop multiplying,vacuum packaging cannot inhibit the reproduction of anaerobic bacteria and the deterioration and discoloration of food caused by enzymatic reactions, so it needs to be combined with other auxiliary methods, such as refrigeration, quick freezing, dehydration, high temperature sterilization, radiation,irradiation sterilization, microwave sterilization, salting etc.
