With the improvement of people's living standards, people's requirements for the quality of food that they depend on are also increasing day by day. Everyone hopes that every day's food is fresh and delicious! However, some food packaging that appears on the market is always unsatisfactory. Now a brand-new packaging nitrogen-filled packaging meets this demand of people.

Fill the food packaging bag with nitrogen to isolate the ground contact of food, fruit, etc. with the air, and prevent the oxidation, fading, and corruption of the food caused by direct contact between the atmosphere and various packaged foods, as well as the effects of various molds and bacteria on the food. Infringement, so as to ensure the freshness of packaged food and extend the storage period of packaged food! This method, due to the special physical properties of nitrogen gas is different from chemical anti-corrosion treatment, so it will not leave any residue.

At present, this packaging has been widely used in the packaging of various foods such as potato chips, jerky, fresh fruits, vegetables, nuts, biscuits, etc.! Such a good packaging effect and the resulting economic benefits have been recognized by food manufacturers and users. A certain amount of nitrogen is filled into the beverage tea packaging that people often use to isolate it from the air. The tea in this type of packaging still looks new in color after one year, and the tea fragrance is overflowing! Tea tasters can't tell whether it's new tea? Chen Cha? On the other hand, the tea leaves that are not packaged with nitrogen will turn yellow and black within a short period of time, and the taste is shaking. This example is enough to illustrate the extraordinary effect of nitrogen in food packaging.

In the storage and transportation of food, the role of nitrogen is even more breathtaking. Traditional food storage uses chemical steaming to prevent pests. Nitrogen-filled storage is a storage method that is completely physical and does not leave any residue. In addition, nitrogen is an inert gas, so there is no hidden danger. Therefore, this method is healthy, economical, safe and reliable. It can be described as killing two birds with one stone. During the storage and transportation of fresh fruits and vegetables, when the temperature is adjusted to the optimum refrigeration temperature suitable for the storage, the respiration rate of these storages will decrease, but they are still breathing. Some substances that can cause chemical changes remain There is a chemical change... What can I do? The results of repeated practice have proved that if the storage box is filled with nitrogen to balance the carbon dioxide, oxygen, etc., these phenomena will hardly appear in the storage. In comparison, the shelf life of nitrogen-filled storage is at least ten months longer than that of non-nitrogen-filled storage. Nitrogen storage is particularly effective for perishable fruits such as apples, bananas, pears and oranges. The economic and social effects brought about by the use of chemical preservatives are even more extraordinary. At present, this method has been adopted by many domestic and foreign manufacturers, merchants, and farmers. Nitrogen is used in the nitriding treatment of metals; the nitrogen protection in the cable production process; the applications of electronic products, medicine, petrochemical industry, etc. are everywhere! Therefore, choosing a nitrogen generator not only provides you with high-purity nitrogen, but also has low nitrogen production costs, which saves you a lot of costs, so that you can recover costs as soon as possible and obtain corresponding economic benefits!
