Basic characteristics of cigarettes
Cigarette specifications: length - the domestic cigarette market mainly includes 84 mm, 100 mm, 90 mm and 70 mm in diameter - most of the cigarettes produced by domestic cigarette companies are 7.7 mm and imported cigarettes are 7.8 mm. The internationally popular cigarette specifications are A cigarette with a diameter of 84 mm and a diameter of 7.8 mm is the cigarette specification calculated by the world cigarette industry through scientific experiments on smokers for hundreds of years. In recent years, the State Tobacco Monopoly Administration has actively promoted the development of slim cigarettes. For a period of time, thin cigarettes refers to cigarettes with a diameter of less than 7.7mm. As for the length of cigarettes, it may be for aesthetic reasons, which are often longer than the usual 84mm, about 90-100mm. The shape is slender and slender. In order to further unify and improve the standard of slim cigarettes, the State Tobacco Monopoly Administration issued the "Notice on Regulating and Supporting the Development of Thin Cigarettes", which clarified that the circumference of slim cigarettes is 17.0±1mm. [2] Air permeability of cigarettes: The air permeability of cigarettes is determined by the wrapping paper of the cigarette wrapping paper and the filter tip. Excessive air permeability of cigarettes has a great impact on the smoking effect. Due to the increase in the proportion of air mixed in the smoke, the tar and nicotine in the cigarettes can be diluted to make the smoke more mellow. As time and depth increase, the result is a greater impact on health. Air permeability test method: Hold the cigarette in the mouth, block the other end and blow for a few times. Cigarette moisture: The best moisture content of cigarettes is 11-12%. Under normal circumstances, cigarettes with less than 7% or more than 14% cannot be smoked. It should be brought back to the standard range before smoking. Cigarette weight: The actual weight of shredded tobacco and the filling capacity of the cigarette determine the number of puffs of the cigarette. In the international cigarette market, the cigarettes produced in Japan are the lightest, so the number of puffs smoked is the least. Too high or too low a cigarette weight has an impact on health and smoking effects. When smokers buy cigarette products, they should feel the weight of cigarette products with their hands according to their own experience.
