Vacuum packaging bag is a more popular packaging bag nowadays. How about using vacuum packaging bag to vacuumize money collection? The so-called vacuum, in fact, is to take a plastic bag to dry the air, put the money in it to isolate the air and keep it from being oxidized. Xiaobian saw a very interesting collection. The fifth set of RMB collected by a local tyrant, that is, the 10 yuan denomination paper money that we spend now, has also been packed in vacuum!

This collector claimed to have collected for the first time. He must have read many people's opinions on how to do well in vacuum collection and how to ensure that the appearance of coins is not oxidized and so on. However, the item of not being oxidized is for coins. The material of banknotes determines that the banknotes can not be oxidized completely. Naturally, there is no need to use vacuum packaging at all.
Can the paper money be stored in vacuum packaging to ensure its appearance? The answer is no!
Compared with coins, paper money itself is easy to be destroyed. But not to mention anything else, after being vacuumed by this kind of mesh bag, the pressure outside the bag is enough to make the banknote itself press out a pile of grids. In this way, it will damage the appearance. How can we protect it?
However, this is not the most important thing. The most important thing is that the paper money itself needs a certain degree of humidity. If it is completely vacuum packed, it will only change the quality of the banknote. After a long period of vacuum, the paper money will become brittle, just like a chocolate covered popsicle or beef jerky. This is tantamount to destroying banknotes and directly turning your collection into scrap money!
Therefore, don't make too many meaningless things for the sake of collection, otherwise it will only backfire.
