Forming paper coated with natural plant extract on both sides and preparation method thereof

Abstract

The invention relates to forming paper with both sides coated with a natural plant extract and a preparation method of the forming paper. The forming paper is prepared by the following steps: a natural plant material is subjected to reflux extraction by ethyl alcohol with the volume concentration being 80%, filtering and concentrating are performed to obtain a concentrated extracting solution, the concentrated extracting solution is diluted by a mixed solvent of propylene glycol and absolute ethyl alcohol, so as to obtain a coating solution; then the front and back sides of the forming paper are coated with the coating solution by a paper coating machine, and drying, rolling and winding are performed, so the forming paper is obtained. The natural plant material is one or a composition of multiple of liquorice root, tobacco stem, orange peel and lignum aquilariae resinatum; the total coating amount of the coating solution on the front and back sides of the forming paper is 0.1 to 5.0g / m<2> counted by dry matter. The preparation method is simple, the prepared forming paper with both sides coated can be used for effectively promoting the fragrance concentration and smoke texture of cigarettes, improving the comfort of the cigarettes and manifesting the brand style characteristics better, and has good market application prospect.

Description

technical field [0001] The invention relates to the technical field of cigarette accessories, in particular to the technical field of forming paper, in particular to a forming paper coated with natural plant extracts on both sides, and further, the invention also relates to a preparation method of the forming paper. Background technique [0002] As one of the important components of the "three papers and one rod" of cigarettes, the filter plug forming paper is a special paper used to wrap the filter rod tow, and is located between the inner tow and the outer tipping paper in the structure of the cigarette filter rod. According to different air permeability, forming paper is divided into ordinary forming paper and high permeability forming paper. Usually formed paper is mainly composed of wood pulp fibers and inorganic materials, which will produce paper fiber smell during the suction process. In order to improve the smoking quality of cigarettes, in the prior art, a certain...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the current existing technologies are all methods of coating the functional material liquid on the side of the forming paper wrapping the tow, and the coating amount of the functional component is small, and there is often the problem of inconsistent sensory quality between the front and rear sections of the cigarette.
