What's the packing of the air in the food package?
For example, our common bag of potato chips, which is mostly nitrogen N2, a gas filling packaging is fat, on the one hand is the replacement of the original air bag and prolong the shelf life; on the one hand, there is a large amount of gas support chips during transportation and storage, can also be to reduce the impact of fragmentation. You certainly don't want to buy potato chips all over it.
Carbonated drinks are mostly filled with carbon dioxide gas CO2, and its own drinks are carbon dioxide ingredients in the majority, with CO2 replacement of the air, but also for the preservation of the product, to ensure the taste, but also improved the shelf life.In addition, some food packaging is filled with a certain proportion of mixed gas, may be O2+CO2+N2, N2+CO2, O2, +CO2. This is also based on the needs of different enterprises, different customers.
At present, there are many inflatable packaging name, nitrogen packaging, air conditioning packaging. These are the use of a gas replacement method, to achieve the effect of food insurance. Food is too afraid of oxygen, excessive exposure, long exposure to oxygen, may occur oxidation, metamorphism and other issues. Filling the package with a certain amount of inert gas will effectively prolong the shelf life of the food.
