Look at cigarettes

1. The roll paper and tipping paper of real "Zhonghua" cigarettes are printed with words or patterns consistent with the outer packaging. Authentic filter rods are generally acetate fiber filter rods, which have good elasticity, full and uniform cut tobacco, uniform and complete cigarette shredding and smooth surface.

Taste and suck

The real "Zhonghua" cut tobacco has the natural aroma of mixed essence, soft fragrance, rich and pure smoke, pure and moderate taste and good combustibility.

Second, how to preserve China cigarettes?

Temperature and humidity are particularly critical. It is best to control the temperature at about 4 degrees Celsius and the humidity at 60%. At the same time, although tobacco has been specially treated, it should also be prevented from being eaten by insects. It's best not to open the package. If you keep it at home, you can put it in the refrigerator. Since you have so many, you might as well find a cold and sealed place.

Generally, it is best not to store cigarettes for more than two years, otherwise, even if the cigarettes are not moldy and deteriorated, 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.

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.
