An inner surface wrinkled cigarette paper

Abstract

The invention discloses cigarette paper with a crinkled internal surface. The cigarette paper is prepared from 40wt% or above of long fiber and 40wt% or above of bast fiber; further, the internal surface is coated with 3wt% or above of vegetal toughness intensifier; further, the gram weight of the cigarette paper is more than 28g / m<2>; the quantity of crinkles within an area of 54mm*26.2mm is more than 30; the depths of the crinkles are 0.01mm to 0.05mm; the specific surface area of the internal surface is 1.3 to 1.5 times of an original surface area. The invention also discloses a preparation method of the cigarette paper with the crinkled internal surface.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a cigarette paper with a wrinkled inner surface and a preparation method thereof. Background technique [0002] Cigarette paper belongs to thin paper, and the general basis weight is 26-34g / m 2 Among them, cigarette paper, as the packaging paper of cigarette products, occupies a more important position in the tobacco industry. Cigarette paper generally accounts for 5% of the total weight of cigarettes. Because it directly participates in combustion, cigarette paper can affect the flammability, flavor, and tar production of cigarettes by controlling the flammability of cigarettes and the dilution of smoke. And other harmful components of smoke, especially the production of carbon monoxide. [0003] In order to prevent faulty cigarettes such as short ends and air leakage, the cigarette making machine increases the filling amount of shredded tobacco at the burning end ...

AI Technical Summary

Problems solved by technology

[0004] Due to the structure of the cigarette, the shredded tobacco at the front end of the cigarette is exposed to the outside. During the cigarette rolling process, the packing density of the shredded tobacco at the end of the cigarette that has been increased by the cigarette rolling machine is reduced, so that the tightness of the end of the cigarette is improved. To a certain extent, it can effectively reduce the empty end of cigarettes and the ends of the ends, but because the filling of the ends of cigarettes is too thick, there are generally the following problems: (1) During the cigarette processing process, the proportion of cut stems added increases, if The shredded stems are processed at the end of the cigarette, which is easy to cause the cigarette to burst when it is burned, resulting in fly ash; (2) due to the thick filling of the cigarette, the shredded tobacco inside the cigarette is not fully burned, and the quality of smoking is reduced; (3) the current shredded tobacco Different types of shredded tobacco (stems, expanded stems, reconstituted tobacco leaves, shredded leaves, etc.) in the formula have different widths, lengths, and filling values. In the state of transportation or the movement of the cigarette box, it is easy to cause the end of the cigarette to fall off and be empty or turn around.
