Method for preventing displacement of fuming medium in cigarette and reducing cigarette paper combustion risk

Abstract

The invention belongs to the field of heating cigarettes, and particularly relates to a method for preventing displacement of a fuming medium in a cigarette and reducing a cigarette paper combustion risk. The method comprises the step of wrapping a fuming medium section of a cigarette with flame-retardant cigarette paper. The flame-retardant cigarette paper comprises a paper layer (1) and a plurality of aluminum foil strips (2). The flame-retardant cigarette paper is prepared through the following steps that the multiple aluminum foil strips (2) are compounded on the inner side of the paper layer (1), and a gap is formed between two adjacent aluminum foil strips (2). When the flame-retardant cigarette paper is used for wrapping the fuming medium section, on one hand, the plurality of aluminum foil strips (2) compounded on the inner side of the paper layer (1) can reduce the combustion risk caused by over-high heating temperature of the cigarette paper; on the other hand, the aluminum foil strips (2) have a certain thickness, and a plurality of groove structures are formed in the inner side of the paper layer (1), so that the friction force between the fuming medium and the inner side of the cigarette paper is increased, and the displacement risk of the fuming medium in a cigarette is reduced.

Description

technical field [0001] The invention belongs to the field of heated cigarettes, and in particular relates to a method for preventing the displacement of the smoking medium in the cigarette while reducing the burning risk of the cigarette paper. Background technique [0002] In recent years, with the strengthening of the public's awareness of the dangers of cigarettes and the strengthening of government regulations on cigarettes, the international traditional cigarette market has been gradually declining. At the same time, new tobacco products have grown rapidly against the trend. Among them, the sales volume of heated cigarettes is increasing year by year, especially electric heated cigarettes are popular in the market, and its technical maturity and smoking experience are far ahead of other new tobacco products. [0003] Currently, in order to prevent the tobacco from burning, the heating temperature of cigarettes is relatively low, about 300° C., which will lead to limited...

Problems solved by technology

However, after the composite aluminum foil wraps the smoking medium section, the aluminum foil layer in contact with the smoking medium is relatively smooth, and the friction between the two is relatively small. Longitudinal displacement or detachment
