With the development of cigarette technology and increasingly intense competition in the tobacco industry, the technical content and differentiated individual elements of products become key factors for the sustainable survival and the long-term development of the products. Due to the limitation of the traditional cigarette auxiliary materials on application characteristics, the application of the functional cigarette auxiliary materials becomes an important technical means for improving the technical content of products gradually. With the development requirements of tar reduction, harm reduction, aroma enhancement and moisture retention in the tobacco industry, more and more attention is paid to the research of the forming paper. The traditional forming paper has single function, sometimes has paper peculiar smell, and reduces the smoking quality and the taste of the cigarette. Under the condition that the requirements for the specialization and individuation of cigarette products are continuously improved, the novel filter stick forming paper is researched and developed through technical improvement on the basis of the existing filter stick forming paper preparation process, so that the inherent peculiar smell of the forming paper can be covered, the smoke can be modified, the cigarette aroma quality can be improved, and the cigarette sensory smoking quality is improved.
At present, the research on functional forming paper is more applied, namely the effects of increasing aroma and keeping moisture are achieved by coating forming paper liquid or an auxiliary agent; the other type is that the forming paper is coated with a functional coating, and the aim of reducing harm and reducing tar is achieved by the adsorption effect of the coating. Chinese patent CN 102433793 discloses a flavoring method for filter stick forming paper, which is to extract aroma components from NC82 tobacco powder or tobacco shreds planted in Shilin of Yunnan by ethanol, and coat the aroma components on the forming paper, thereby realizing the purposes of improving the aroma concentration of cigarettes, harmonizing the fragrance of the cigarettes, improving the comfort and improving the quality of the cigarettes. Patent CN 203226265 discloses a filter stick containing functional traditional Chinese medicine auxiliary agent, wherein a functional traditional Chinese medicine auxiliary agent layer is coated on the surface of the forming paper of the filter stick. The traditional Chinese medicine auxiliary agent emits fragrance similar to the fragrance of the tobacco after being heated, can improve the fragrance of cigarettes and make up for the deficiency of the fragrance of smoke, can reduce harm and reduce tar, can keep the original fragrance style, and has obvious effect of improving smoking taste. Patent CN 101721976 discloses an antibacterial adsorbent and a method for applying the adsorbent to forming paper, the antibacterial adsorbent is composed of tea polyphenol, attapulgite, medical stone and copper-loaded activated carbon, the granularity of each component is 100 meshes, the tea polyphenol is dissolved, the attapulgite, the copper-loaded activated carbon and the medical stone are mixed and then are attached to the surface of forming base paper wrapping one surface of a filter stick through a binder dissolved with the tea polyphenol to form an adsorption layer with the thickness of 0.05-0.1mm, the antibacterial adsorbent is mainly used for selectively adsorbing carbon monoxide and tar in smoke, and has a certain adsorption effect on nicotine, acetone, gas-phase free radicals, benzopyrene and nitrite.
Although the technologies improve the appearance color of the formed paper to a certain extent, improve the identifiability of the formed paper, have a certain unique style and improve the taste of cigarettes, the coating amount of effective components is small by a feed liquid dip-dyeing coating method, and the spice substances are lost to a certain extent in the extraction process, the process is complicated, the yield is not high, solvent extraction can bring some foreign substances, and simultaneously the problem of solvent residue exists, which affects the taste of cigarettes, and in addition, the problems of volatilization loss of the spice substances in the storage process and inconsistent front and back sections in the smoking process exist in the coated formed paper.
