The Advantages of Milk Powder and Milk Powder Packaging
Milk powder is a dairy product that retains the valuable nutrients in milk by evaporating the liquid part of the milk, leaving behind a dry powder. This process extends the shelf life of the product and increases its convenience, saving space and reducing transportation costs.

Benefits of Using Nitrogen in Milk Powder Packaging
Prevent Oxidation and Extending Shelf Life
By filling nitrogen to the package to replace oxygen, an oxygen-free or low-oxygen environment can be achieved inside the package. It helps to prevent oxidation of milk powder. What’s more, nitrogen is an inert gas that does not react with food. This helps to prevent the growth of fungi, bacteria and other microorganisms, stops milk powder from spoiling and extends its shelf life.
Moisture Protection
Nitrogen helps prevent moisture from entering the package. Moisture can cause milk powder to clump and grow bacteria that can cause product spoilage. Filling nitrogen to the package can help maintain a dry environment inside the package.
Aroma Preservation
The unique aroma of milk powder is very important to a good quality milk powder product. The moment you open the milk powder package, you will surely prefer the strong milk aroma to a milk powder product with no milk aroma. Oxygen and moisture will cause the aroma to fade. Filling nitrogen to the package will greatly reduce the interference of oxygen and moisture. This will help to keep the aroma of the milk powder and maintain the freshness.
