Why do you seldom see the expiration date on cigarette boxes?

Smoking is harmful to health. Look, this is the slogan that people often say no smoking. Basically, even three-year-old children know this sentence, but it is well known that old smokers who smoke often still have a soft spot for smoking, and people are under great pressure now. When I am stressed, I like smoking to release my stress. The price of cigarettes on the market ranges from a few to several thousand. I wonder if you have observed them carefully when you buy cigarettes. Generally, the shelf life is rarely seen on bulk cigarette cases. Why? Today, we will talk about this problem. Why do you seldom see the shelf life on cigarette cases? Say the answer, you may not think of it!

First of all, let's learn about the manufacturing process and composition of cigarettes. Cigarettes are mainly made of dry tobacco leaves. Because freshly dry-baked tobacco leaves will greatly affect the taste, they will generally be preserved for a period of time. However, if this process is not properly preserved, it will be damp and moldy, which will affect the taste. If there is no shelf life, it is impossible to know how long this tobacco leaf has been kept! There is also that everyone usually buys cigarettes in bulk in a whole box, while the cigarettes produced by the factory are all made in one piece!

Merchants who sell cigarettes usually buy cigarettes as a whole. Because of the customer's demand, they packed the whole cigarette and sold it! Because the production date of bulk cigarettes is different from that of the whole cigarette, general manufacturers will generally print the production date and shelf life on the whole cigarette packaging box based on the whole cigarette. Because customers usually buy bulk cigarettes, they can't see the shelf life printed on the box, and some small boxes of cigarettes are printed with the shelf life, but because of unclear handwriting or other reasons, it is difficult to see the production date when the batch number and machine number are mixed together!
