we all know that the main effect of vacuum packaging is oxygen, through the packaging of the discharge air to achieve the effect of vacuum and then effectively inhibit bacterial growth, to prevent food spoilage. Its principle is simple, because food metamorphism causing mold mainly caused by the activity of microorganism, and most microorganisms ( Such as mold and yeast) Survival is need oxygen, and the vacuum packing bag is using this principle, the food packaging and food within the cell oxygen smoke, lose micro physical & other; The survival of the environment & throughout; , then not only extend the shelf life of food, food freshness with ascension.

food use vacuum packaging to the packaging is according to the assured, because the vacuum bags in oil resistant, resistant to moisture, resistant to low temperature freezing, with good quality, fresh smell, such as * performance is very stable in performance, got the favour of broad consumer, vacuum packing bag with different plastic materials, high separation performance, co-extrusion film of oxygen, water, carbon dioxide, smell the effect of contour blocks, is the ideal packaging options.

when the concentration of oxygen in the food packaging bags & le; 1%, microbial growth and reproduction rate fell sharply, oxygen concentration & le; 0. 5%, most microbes will end by inhibition and reproduction. （ Note: vacuum bags can inhibit anaerobic bacteria reflect the cause of food spoilage and color reproduction and enzymes, so still need to combine with other adjuvant way, such as cold storage, frozen, dehydrated, high temperature sterilization, irradiation sterilization, microwave sterilization, salting, and so on.
