preparation example Construction

[0014] The preparation of tobacco fiber pulp is to wash tobacco raw materials such as tobacco powder, tobacco stems, tobacco stalks, waste tobacco shreds, waste tobacco leaves, etc., prepare the materials into fragments no larger than 2cm, filter and remove dust, and add water to cook; the pulping conditions are: cooking temperature The temperature is 80-145°C, the pressure is normal pressure-0.3MPa, the amount of alkali used is 0-12%, the cooking time is 30-90 minutes, and the solid-liquid ratio is 1:3-6. Filtrating, extruding, washing and removing impurities to obtain tobacco fiber pulp. The preparation of hemp fiber pulp adopts the existing material preparation and pulping technology, and is prepared from hemp raw materials such as hemp bast, flax bast, kenaf bast, sisal hemp, Manila hemp and the like.

[0015] According to needs, only part of the pulp can be replaced on the back layer and surface layer of the cardboard.

[0016] The bleached softwood pulp, bleached broadl...

Embodiment 1

[0018] Take by weighing 30.0kg of tobacco fiber pulp, 25.0kg of hemp fiber pulp, and 65.0kg of bleached broadleaf pulp, fully mix them evenly in the pulp mixing tank, and then add retention aids and filter aids to the mixed pulp according to the existing papermaking technology etc., stir evenly, then dilute to the online concentration, pass through the headbox, and form the cardboard back layer and surface layer on the lapping paper machine (the core layer still adopts the fiber type and proportion used in the prior art), and pass through together Pressing, drying, light sizing, light coating on the surface layer, calendering, coiling, and slitting can obtain the novel cigarette pack paper of the present invention.

Embodiment 2

[0020] Weigh 10.0 kg of tobacco fiber pulp, 25.0 kg of hemp fiber pulp, 10.0 kg of bleached coniferous pulp, and 55.0 kg of bleached broadleaf pulp. The preparation method is the same as in Example 1.

Abstract

The invention relates to novel cigarette packet paperboard, which comprises a core layer, a surface layer and a back layer. The surface layer and the back layer of the paperboard are mixed fiber pulp paper containing tobacco fibers and hemp fibers; and mixed fiber pulp comprises the following components in percentage by weight: 6 to 30 percent of tobacco fiber pulp, 5 to 25 percent of hemp pulp, 0 to 25 percent of bleached softwood pulp and 40 to 70 percent of bleached hardwood pulp. A part of bleached softwood pulp or bleached hardwood pulp used by the surface layer and the back layer of the cigarette packet paperboard is replaced by the tobacco fibers and the hemp fibers, so that cost can be reduced, quality can be ensured, and strength is qualified.

Description

technical field [0001] The invention belongs to the technical field of cigarette packaging material production, and in particular relates to a cigarette pack paper added with natural tobacco fibers and hemp fibers. Background technique [0002] Cigarette cases are mainly used to protect cigarettes and facilitate storage and transportation of cigarettes. The paper currently used to make cigarette boxes is mainly hard-packed white cardboard and soft-packed coated paper, both of which are high-grade packaging papers. The main fiber raw materials are imported bleached softwood pulp and bleached hardwood pulp, and the cost is relatively high. . Commonly used cigarette pack paper is generally divided into surface layer, core layer and back layer. Generally, the surface layer and the back layer are produced with bleached coniferous pulp and bleached broadleaf pulp in different proportions to meet the requirements of high whiteness, high stiffness, and high folding resistance; the...
