Cigarette stamps are generally composed of letters and numbers. The steel seal of the whole cigarette is generally printed on the trademark paper at both ends, and some are printed on the side. The steel seal of the small box is printed on the bottom trademark paper, and there is generally no steel seal on the bottom trademark paper of soft cigarettes. Except for a few cigarettes, the steel seal of soft cigarettes is generally printed on aluminum platinum paper, which can't be seen from the outside.

Second, the arrangement

The letter or number arrangement of real cigarette steel seal is generally high or low, uneven, and the spacing between letters or numbers is uneven, especially the spacing between letters and numbers is generally obviously large. Because the real cigarette steel seal is dynamically printed by the machine on the packaging production line, the steel seal arrangement is irregular. Because fake cigarettes usually print trademark paper first and then imitate real cigarettes to print steel seals, and the steel seals are printed under static conditions, the steel seals of fake cigarettes are generally uniform, with equal spacing and uniform size and thickness.

Third, depth.

Attention should be paid to the situation of real cigarettes boxed with fake cigarettes in actual operation. Identifying whether trademark paper is reused depends on whether the sealing technology and anti-counterfeiting technology of transparent paper are inconsistent with the real cigarette technology, and whether there are secondary creases and secondary gluing on the back of small boxes (hard bags), so as to more accurately identify the authenticity of cigarettes.

What are the hazards of fake cigarettes?

Fake cigarettes, as the name implies, are fake and shoddy cigarette products. Both real cigarettes and fake cigarettes are harmful, but real cigarettes are less harmful than fake cigarettes.

At present, the tobacco industry requires that the tar content of cigarettes should not exceed 13 mg per cigarette. In the conventional cigarette processing technology, a series of measures have been taken to reduce coke, such as improving the natural permeability of cigarette paper, various forms of filters, reducing tar content in smoke by punching and diluting, and directly improving the internal structure of cut tobacco by using new technologies such as expanded cut tobacco, cut stem and tobacco flakes.

However, due to the defects in technology, equipment, quality control and raw material selection, it is difficult for fake cigarettes to meet the requirements of reducing coke, so high tar content has always been the most obvious hazard of fake cigarettes. The tar content of some fake cigarettes is as high as 50 mg per cigarette. Inhaling a large amount of fake cigarette tar will greatly increase the risk of inducing various cancers and cardiovascular and cerebrovascular diseases.
