How long is it best to keep cigarettes?

If the whole unopened cigarette depends on the storage environment, generally speaking, the shelf life of cigarettes is about one or two years, but the shelf life of cigarettes will be different due to different storage environments. For example, in high temperature and high humidity environment, cigarettes will go moldy and deteriorate after a summer, while in dry and cold areas, the shelf life of cigarettes can reach more than 2 years.

Under the same circumstances, the unopened storage time of the whole package will be shorter than that of the whole package, and it will be even shorter if the cigarettes can be stored for a few days after unpacking. For the whole package of unopened cigarettes, the storage principle is the same as that of the whole package, but the time will be shortened. Under the condition of good preservation, the whole pack of cigarettes can be preserved for about one year.

According to the practical experience of many tobacco hotel owners, it has a lot to do with storage conditions. Friends who know the cigarette making technology should know that most cigarettes in China are flue-cured tobacco, that is, the tobacco leaves are dried in a special curing barn, shredded and expanded, and then moistened. After the cigarette is made, it should be sealed with two layers of tin foil and cellophane to maintain the best wettability. So cigarettes are very afraid of high temperature, high humidity and sunshine. If the storage conditions are improper, the cut tobacco will easily evaporate and absorb too much water, which will lead to mildew and deterioration. So if it is properly preserved, it will be fine in three to five years, and it will be moldy in less than one year if it is improperly preserved. Due to the vast territory of China, the climate gap between the south and the east and west is huge, and the storage time varies from place to place. Generally speaking, the storage time of cigarettes in the south is shorter than that in the north.
