[Chinese Packaging Network News] In general, infant formula milk cans are mainly canned, but there are also many boxed (or bagged), from the perspective of canning, packaging is much more expensive than boxed, these two What is the difference between the two? I believe there are many clerk and consumers are tangling the problem of milk powder, saying that the direct point is, in the end there is no difference? How much difference? Here to explain.
1, different packaging materials
This point is apparent from the exterior, canned milk powder is mainly used metal and environmentally friendly paper two kinds of materials, metal cans of moisture resistance, pressure resistance are the first choice, although environmental protection paper is not as strong and sealed cans, but convenient for consumers to use , It is also stronger than ordinary carton packaging pressure resistance. The outer layer of boxed milk powder is generally a thin paper shell, and the inner layer is a plastic flexible packaging (bags). The plastic's tightness and moisture resistance are inferior to metal cans.
2, different capacity
Common canned foods on the market have a general capacity of about 900 grams (800g, 1000g are common), and boxed milk powder is generally 400 grams. Some boxed milk powder is 1200 grams. There are 3 small bags of 400 grams of small packaging, and there are 800 Grams, 600 grams, etc.
3, different shelf life
If you look carefully at the shelf life of powdered milk, you will find that canned milk powder and boxed milk powder are very different. Generally, the shelf life of canned milk powder is 2 to 3 years, and the boxed milk powder is generally 18 months. This is because of the canned milk powder. The sealability is better, it is beneficial to the preservation of milk powder, it is not easy to spoil, and it is easier to seal after opening.
4, the storage time is different
Although from the packaging instructions point of view, canned milk can be placed for 4 weeks after opening. However, after opening, boxed/pouched bags cannot be completely sealed, and the effect of shelf life is slightly inferior to canning. This is one of the reasons why bags are generally 400g small packages. On the whole, after the box is opened, it is difficult to preserve the boxed product compared to the canned product. The shelf life is slightly inferior. Generally, it is recommended that the boxed food be eaten within two weeks after opening the box.
5, the composition is basically the same
In general, the canned and boxed milk formula of the same section is basically the same regardless of the ingredient list or the nutritional composition table. The mothers can compare when purchasing, and certainly do not rule out that there will be inconsistencies.
6, the price is different
In general, the unit price of a boxed customer of the same brand will be slightly lower than that of the listener, so some people buy the box because the price is cheaper.
Advice: See age purchase
If it is a small baby to drink milk powder, especially the baby within 6 months, it is best to choose canned milk powder, because milk powder is the baby's main rations, boxed / bagged milk powder is inconvenient to accurately measure, seal It is not easy to get wet or contaminated, and the precise dispensing of milk is related to the baby's nutritional status. The cleanliness of milk powder is related to food hygiene issues.
If it is a larger baby, especially a baby over 2 years of age, milk powder is no longer a staple food, the formulated milk does not need to be so accurate, and the baby's resistance is getting better and better. At this time, you may consider buying a box or a bag. Milk powder can reduce the economic burden. However, it is generally not recommended to pour the packaged milk powder into the iron cans before. This may cause secondary pollution. The packaged milk powder can be stored in a clean and tight can.
