Problems solved by technology

[0002] At present, paper for cigarette boxes and carton packaging is mainly coated white cardboard and coated paper, both of which must use bleached chemical pulp or mechanical pulp. Wood pulp will release many toxic and harmful substances during the bleaching process, such as AOX (adsorbable organic halides), dioxins, etc., with the current domestic production bleaching process, about 2.0-4.0kg of AOX and trace amounts of dioxins will be emitted from the production of one ton of bleached pulp. These substances need to be processed through a very complicated process. treatment in order to meet environmental protection requirements
In addition, there is a kind of black cardboard currently on the market. The base paper is dyed with a large amount of dyes, and a large amount of black dye is added to the primer. Although this product can be made in a different color from white cardboard, it has anti-counterfeiting functions. However, this kind of product will produce very difficult waste water in the production process, which is not conducive to environmental protection requirements. There are also a large amount of chemical substances such as azo dyes in the paper itself, which can easily lead to volatile (VOC S ) and excessive heavy metals

Embodiment 1

[0034] Embodiment 1 (220g / m 2 natural color cigarette cardboard)

[0035] Surface layer pulping: pulp board (chemical pulp long fiber: chemical pulp short fiber = 20:80) is crushed by a hydraulic pulper and then beaten (if it is self-made pulp, it is directly beaten), and then batched to obtain bleached chemical wood pulp.

[0036] Core layer pulping: natural color pulp board (natural color chemical pulp: natural color mechanical pulp = 60:40) is crushed by a hydraulic pulper and then beaten (if it is self-made pulp, it is directly beaten), and then batched to obtain natural color chemical pulp wood pulp.

[0037] Bottom layer pulping: unbleached pulp boards (all unbleached chemical pulp) are crushed by a hydraulic pulper and then beaten (if it is self-made pulp, it is directly beaten), and then batched to obtain unbleached chemical wood pulp.

[0038] The chemicals and their amounts added in the pulping process are: rosin 1.7KG / ton of paper; aluminum sulfate 7.8KG / ton of p...

Embodiment 2

[0044] Embodiment 2 (230g / m 2 natural color cigarette cardboard)

[0045] The production process of this embodiment is basically the same as that of Example 1, wherein the ratio of the long fibers of the pulp and the short fibers of the pulp used in the pulping process of the surface layer is 15:85, and the pulping process of the core layer uses The ratio of natural chemical pulp and natural mechanical pulp is 55:45. All the raw chemical pulp used in the pulping process of the bottom layer is natural chemical pulp. The chemicals and their amount added in the pulping process are: rosin 1.9KG / ton of paper; Aluminum sulfate 8.0 KG / ton of paper; cationic starch 4.9KG / ton of paper; fungicide 1.0KG / ton of paper; defoamer 0.25KG / ton of paper, three-layer quantitative: surface layer: 65 g / m 2 Core layer: 120g / m 2 Bottom layer: 45g / m 2 , the paint used for the coating layer on the surface layer is prepared from 25% china clay, 60% calcium carbonate, 15% latex, 0.15% dispersant, 0.3...

Embodiment 3

[0049] Embodiment 3 (210g / m 2 natural color cigarette cardboard)

[0050] The ratio of chemical pulp long fiber and chemical pulp short fiber used in the surface layer pulping process is 15:85, and the ratio of natural color chemical pulp and natural color mechanical pulp used in the core layer pulping process is 70:30 , all used in the pulping process of the bottom layer is natural chemical pulp. The chemicals and their amounts added in the pulping process are: rosin: 1.5 KG / ton of paper; aluminum sulfate: 7.0KG / ton of paper; cationic starch: 5.0 KG / ton of paper; fungicide: 1.0KG / ton of paper; defoamer 0.2 KG / ton of paper, three-layer quantitative: surface layer: 60g / m 2 Core layer 110g / m 2 Bottom layer: 40g / m 2 , the paint used for the coating layer on the surface layer is prepared from 25% china clay, 60% calcium carbonate, 15% latex, 0.15% dispersant, 0.3% water repellant, and 0.6% lubricant. The cloth weight is 2g / m 2 .

Abstract

The invention discloses a natural-color cigarette cardboard and a production method thereof. The natural-color cigarette cardboard comprises a surface layer, a core layer and a bottom layer, wherein the surface layer is coated with a coating layer and is prepared from bleaching chemical wood pulp; and the core layer and the bottom layer are prepared from natural color chemical wood pulp. The production method comprises the following steps of manufacturing body paper, coating, drying, calendaring for finishing, regulating moisture and the like. The natural-color cigarette cardboard has the advantages of environmental protection, counterfeiting resistance and the like, is clean, conforms to the requirements of paper for food packaging and saves raw materials. The natural-color cigarette cardboard prepared by the production method disclosed by the invention has the advantage of good surface smoothness, and printing performance, composite performance and post processing performance can completely satisfy the requirement of cigarette box and strip packages.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a natural and environment-friendly natural color cardboard for cigarette packaging and a production method thereof. Background technique [0002] At present, the paper used for cigarette boxes and carton packaging is mainly coated white cardboard and coated paper. Both of these two kinds of paper must use bleached chemical pulp or mechanical pulp. Wood pulp will release many toxic and harmful substances during the bleaching process, such as AOX (adsorbable organic halides), dioxins, etc., with the current domestic production bleaching process, about 2.0-4.0kg of AOX and trace amounts of dioxins will be emitted from the production of one ton of bleached pulp. These substances need to undergo a very complicated process. The treatment can meet the requirements of environmental protection. In addition, there is a kind of black cardboard currently on the market. The base paper is...
