The principle of three edge-sealing bag adopts the vacuum bag

As you see 3-side in many cases are using vacuum packaging technology, vacuum packing technology is making the sack at high stress state makes the microbes to survive, to achieve food antiseptic. So why do 3-side is using vacuum packaging technology? A, 3-side adopts the principle of vacuum packing in vacuum packing important thing is to take out air, produce the effect of low oxygen, prevent food spoilage. 3-side adopts the principle of such packaging is very simple also is easy to understand. Because food mould made mainly by microbial activity, and most of the survival of microorganisms need oxygen, so vacuum packing pump oxygen out of the sack, lose microbial survival essentials. 5%, the majority of microbes will be reined in and stop breeding. 3-side using vacuum packaging of another reason is to prevent oxidation of food, because the oil kind food contains a lot of unsaturated fatty acids, which make the bad food. In addition, the oxidation also make vitamin A and vitamin C loss, make the color darker. So oxygen can effectively prevent food spoilage, makes it possible to keep food from the factory to be used and wonderful. Second, 3-side using vacuum packaging and the applicable scope of the reasons: 1, pickled food: mainly is the existence of the consumption of iodized salt, can cause the probability of metamorphic food next time in high temperature conditions; 2, seafood, seafood, in many cases to be preserved, so that it will look great taste; 3, electronic products, mainly for anti-static, prevent product because with electrostatic and burn out; 4, chemical products, chemical products can be volatile, and often have a certain toxicity; 5, parts categories: avoid the loss of parts; Class 6, cosmetics: mainly face film, maintain moisture and good close skin performance. 3-side adopts the current application of vacuum packing with plastic bag vacuum bag, aluminum foil packaging, glass, plastic and composite packaging, etc. Which is particularly common in life, and, due to its long-term use of 3-side got a lot of application, also is in the life, the enterprise of a product.
