In the milk powder area of each maternity store or supermarket, there are a variety of milk powder brands, mainly in the form of tin boxes packing and plastic bag packaging. Most of the milk powder uses tin boxes. Why?
Canned milk powder has a long shelf life
Since bagged milk powder is much cheaper than canned milk powder, why do many mothers choose canned milk powder?
Because canned milk powder can last longer than bagged milk powder. The shelf life of canned milk powder is generally 2 to 3 years. This is because the canned milk powder is generally filled with nitrogen gas, and the isolation from the air is conducive to the preservation of the milk powder, and it is not easy to spoil and deteriorate. It is required to finish eating within 4 weeks after opening the can. The bag is not easy to store, the shelf life is about 1 year, and it is easy to be damaged during transportation. In addition, it is generally required to finish eating within 2 weeks after opening the bag.
