Vacuum packing bag is divided into transparent vacuum bag and vacuum aluminum foil bag, vacuum bag composite materials are usually PE and nylon composite, because nylon has good barrier properties, can effective resistance wet gas blocking, also can maintain a vacuum for a long time, so be the first choice of the public, and ordinary plastic bags more than ordinary plastic, so that the surface of the plastic bag have air hole, not vacuum packing, even if reluctantly packing ok, time is long and prone to leak problem, even just a flat pack. If you want to keep the food fresh for a long period of time, not vacuum can achieve, because when the concentration of oxygen in the packaging & le; 1%, microbial growth and reproduction rate will drop sharply, oxygen concentration & le; 0. 5%, most of the microbial stopped breeding will be reined in, and vacuum packing does not inhibit anaerobic bacteria breeding and enzyme reaction, and therefore easy to cause food spoilage and discoloration, so still need to combine with other auxiliary methods, such as cold storage, frozen, dehydrated, high temperature sterilization, irradiation sterilization, microwave sterilization, salting, and so on.
