How long can unopened cigarettes be kept? How to save it?

The shelf life of cigarettes is about 2 years. Cigarettes can be stored for 1-2 years in a cool, ventilated and dry environment without unpacking; If you wrap cigarettes with plastic wrap, or protect them with professional tobacco protection boxes and put them in the refrigerator, then cigarettes will not expire in 5- 10 years.

Cigarette production date:

1. It is best not to store cigarettes for more than two years. Otherwise, even if the cigarette is not moldy, the taste will change and the quality will be greatly reduced. It is of little significance to save all kinds of cigarettes that you have worked so hard to collect. It is better to collect all kinds of beautiful incense labels.

2. When regular cigarettes leave the factory, the specific production date will be clearly marked on the large packaging box and product certificate, but most manufacturers do not clearly mark each cigarette and box, and the national tobacco authorities have no unified regulations in this regard. Manufacturers, distributors and quality supervision and monitoring professionals in all aspects of the tobacco industry generally know the specific production date of cigarettes, but only "smokers" as consumers cannot know. At present, there is no brand of cigarettes in China that will indicate the shelf life, and cigarettes in many foreign countries do not indicate the shelf life.

Extended data:

A cigarette is a tobacco product. The production method is to dry tobacco and shred it, and then grow it into a barrel-shaped strip with a diameter of 120mm in a paper roll. When smoking, one end is lit, and then the smoke is breathed through the mouth at the other end. Cigars are smoked by rolling tobacco into cylindrical strips. The main difference between cigarettes and cigars is that cigarettes are smaller and tobacco is finely chopped. Cigarettes were first popular in Turkey, and locals like to roll up tobacco with newspapers and smoke it.
