Analysis Of Multilayer Structure Of Vacuum Bag

Oct 30, 2017

Composite vacuum BAG multi-layer structure can effectively dustproof, anti-fouling, isolating gas, anti-ultraviolet, decorating and printing, the application advantage is very obvious, in daily life, compound vacuum bag application in the food packaging industry most common, especially perishable perishable food applications are especially common.Vacuum Bag 

Packaged food with a compound vacuum bag, not only can protect food with the outside air and bacterial virus isolation, to prevent food spoilage, to ensure its safety and health, the use of composite vacuum bag can also prevent the food in the oil will not be in the outer packaging of the printing effect of damage, so as to enhance the product in the minds of consumers impression, Good for food marketing.Vacuum Bag

China's composite vacuum bag production from the beginning of the 80 's, after more than 20 years of development and expansion, the current domestic composite vacuum bag production industry has grown mature, has formed a self-sustaining composite vacuum bag packaging production industry, the level of professional technology has been improving, The application of the production line has greatly improved the production efficiency of the compound vacuum bag, and effectively promoted the development and progress of the compound vacuum bag production industry. With the further promotion of composite vacuum bag application, the composite bag will be applied to more industries, and the market development space will be further expanded.Vacuum Bag

When the oxygen concentration in the bag is ≤1%, the growth and reproduction rate of the microorganism drops sharply, and when the oxygen concentration ≤ 0.5%, most microorganisms will be inhibited to stop breeding. (Note: Vacuum packaging can not inhibit the reproduction of anaerobic bacteria and enzyme-induced food spoilage and discoloration, and therefore need to be combined with other ancillary methods, such as refrigeration, frozen, dehydration, high-temperature sterilization, irradiation sterilization, microwave sterilization, salt pickling and so on. )Vacuum Bag

In addition to inhibiting the growth and reproduction of microorganisms, the other important function of vacuum oxygen removal is to prevent food oxidation, because the oil food contains a large number of unsaturated fatty acids, by the role of oxygen oxidation, so that food stale, spoilage, in addition, oxidation also makes vitamin A and C loss, food pigments in the unstable substances in the role of oxygen, so that the color dimming. Therefore, the removal of oxygen can effectively prevent food spoilage, maintain its color, aroma, taste and nutritional value.Vacuum Bag
