Milk powder is mostly packaged in metal cans because the latter have high barrier properties and good sealing properties. Between the two processes of milk powder filling and sealing, the milk powder can must be vacuumed and filled with nitrogen to ensure that the residual oxygen rate in the milk powder can is less than 3%.
If the sealing of the milk powder can is not good, the nitrogen in the can will be lost, and the oxygen and moisture in the air will enter the can. Since milk powder contains a lot of high-nutrient substances such as protein and fat, it is easy to have quality problems such as slow oxidation, deterioration, caking, abnormal color and taste after long-term contact with oxygen. Therefore, the importance of the sealing performance of the milk powder can is obvious.
