Embodiment 1

[0052] In the present embodiment, the tobacco fiber and tobacco extract concentrate are obtained by the following method: according to the solid-liquid ratio of tobacco raw material and hot water of 1:5, the tobacco raw material and hot water are weighed for mixed extraction, and the extraction time is 30 min, and the hot water temperature At 50° C., the extracted tobacco raw materials are subjected to mechanical extrusion to achieve solid-liquid separation to obtain tobacco extract and tobacco fibers. The tobacco extract is heated and concentrated to obtain a density of 1.17-1.19g / cm 3 of tobacco extract concentrate.

[0053] The Tencel fiber described in this embodiment is Lenzing Tencel, the fiber thickness is 1.4 dtex, and the length is 2 mm.

[0054] The softwood pulp fibers described in this example are unbleached natural softwood pulp fibers.

[0055] This embodiment provides a method for preparing a tobacco-type inner lining base paper. The raw materials are prepared...

Embodiment 2

[0058] In this embodiment, the tobacco fiber and tobacco extract concentrate are obtained by the following method: according to the solid-liquid ratio of tobacco raw material and hot water of 1:6, the tobacco raw material and hot water are weighed for mixed extraction, and the extraction time is 45 min, and the temperature of the hot water is 45 min. At 60°C, the extracted tobacco raw materials are subjected to mechanical extrusion to achieve solid-liquid separation to obtain tobacco extract and tobacco fibers. The tobacco extract is heated and concentrated to obtain a density of 1.17-1.19g / cm 3 of tobacco extract concentrate.

[0059] The Tencel fiber described in this example is Lenzing Tencel, the fiber thickness is 3dtex, and the length is 10mm.

[0060] The softwood pulp fibers described in this example are unbleached natural softwood pulp fibers.

[0061] This embodiment provides a method for preparing a tobacco-type inner lining base paper. The raw materials are prepa...

Embodiment 3

[0064] In the present embodiment, the tobacco fiber and tobacco extract concentrate are obtained by the following method: according to the solid-liquid ratio of tobacco raw material and hot water of 1:8, the tobacco raw material and hot water are weighed for mixed extraction, and the extraction time is 60 min, and the hot water temperature is 60 min. At 80°C, the extracted tobacco raw materials are subjected to mechanical extrusion to achieve solid-liquid separation to obtain tobacco extract and tobacco fibers. The tobacco extract is heated and concentrated to obtain a density of 1.17-1.19g / cm 3 of tobacco extract concentrate.

[0065] The Tencel fiber described in this embodiment is Lenzing Tencel, the fiber thickness is 1 dtex and the length is 3 mm.

[0066] The softwood pulp fibers described in this example are unbleached natural softwood pulp fibers.

[0067] This embodiment provides a method for preparing a tobacco-type inner lining base paper. The raw materials are pr...

Abstract

The invention provides tobacco type lining base paper as well as a preparation method and application thereof, the tobacco type lining base paper comprises a fiber raw material, and the fiber raw material comprises the following components in percentage by weight based on the total weight of the fiber raw material: 10-20% of tencel fiber, 25-45% of softwood pulp fiber and 35-65% of tobacco fiber. The tobacco fiber is added into the lining paper base paper, and the tobacco element is endowed to the cigarette packaging material, so that the whole box of cigarettes have better tobacco smell, on one hand, the effect of smelling fragrance after unpacking is achieved, the personality and style of products are highlighted, meanwhile, the loss of the cigarette fragrance of cigarette products in the cigarette box packaging material is effectively reduced, and the cigarette quality is improved. On the other hand, the strength of the lining base paper can be improved. Therefore, the invention effectively overcomes various defects in the prior art and has high industrial utilization value.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a tobacco-type inner lining base paper and a preparation method and application thereof. Background technique [0002] Cigarette lining paper is the wrapping paper lining the inner layer of the cigarette case, and it is an important cigarette packaging material. style and character. The existing cigarette inner lining paper mostly adopts composite aluminum foil paper, and its surface is covered with aluminum film, so that the discarded cigarette inner lining paper cannot be naturally degraded, resulting in waste of metal aluminum and pollution to the environment. In recent years, tobacco companies have reached consensus on green packaging and low-carbon development, making full use of high-tech, new technology and new materials to gradually promote the transformation of traditional composite aluminum foil paper to aluminum-free lining paper for cigarettes. [0003] Aluminum-fre...
