Embodiment 1

[0012] Embodiment 1, this embodiment adopts the low-concentration beating method, by adding a certain proportion of neutral sizing agent (AKD) and wet strength agent polyamide polyamine-epichlorohydrin resin (PAE) in the pulp, and polyethylene Imine (PEI) or cationic polyacrylamide (CPAM) and cationic starch are binary retention aids, which can improve the retention effect of fine fibers, auxiliary materials and additives, and make the base paper have good evenness. The compound method of printing agent and oxidized starch enables the base paper to obtain a certain resistance to fluid penetration, improve shape stability, improve the wet strength of base paper and reduce lateral wet deformation, meet the requirements of accurate overprinting, and produce water-based flexographic printing. The specific production steps of base paper for cigarette tipping paper required by the process are as follows:

[0013] a. Beating section: double-disc mills are used for continuous beating,...

Embodiment 2

[0021] Embodiment 2, this embodiment adopts the low-concentration beating method, by adding a certain proportion of neutral sizing agent alkyl ketene dimer (AKD) in the pulp, and using polyethyleneimine (PEI) or cationic polypropylene Amide (CPAM) and cationic starch are binary retention aids, which can improve the retention effect of fine fibers, auxiliary materials and auxiliary agents, and make the base paper have good evenness. In this way, the base paper can obtain a certain resistance to fluid penetration, improve shape stability, improve the wet strength of the base paper, reduce the transverse wet deformation, meet the requirements of accurate overprinting, and produce cigarette tipping that meets the requirements of the water-based flexographic printing process. Paper base paper, its specific production steps are as follows:

[0022] a. Beating section: double-disc mills are used for continuous beating, the beating concentration of softwood pulp is 3.6%, and the beati...

Abstract

The invention relates to a production method of body paper for tobacco-use tipping paper. The production method produces the body paper for the tobacco-use tipping paper, which satisfies the use requirements of a water-based ink flexography process, by using a low-concentration pulping method, a method of adding neutral sizing agent and wet strength agent in pulp and coating a mixture consisting of surface printable agent and oxidized starch on the surface or a method of adding the neutral sizing agent in the pulp and coating a mixture consisting of printable agent, oxidized starch and wet strength agent on the surface. In the condition of ensuring the fiber strength, the method tries to minimize the fiber devillicate and brooming phenomena so as to ensure smaller wet deformation and better shape stability of the body paper. The body paper for the tobacco-use tipping paper, which is produced by using the method, differs obviously from the traditional gravure body paper, has the advantages of great wet tensile strength, small transverse wet deformation, good glossiness, high anti-picking strength and accurate chromatography, thoroughly satisfies the requirements of the water-based ink flexography process, is a novel body paper for the tobacco-use tipping paper and meets the requirements of printing enterprises in developing healthy and environment-friendly products.

Description

technical field [0001] The invention relates to paper for cigarettes, in particular to a production method of base paper for tipping paper for cigarettes. Background technique: [0002] In response to the international public health treaty "Framework Convention on Tobacco Control" issued by the World Health Organization and the State Tobacco Monopoly Administration's "Opinions on Strengthening the Management of Cigarette Packaging", curb excessive packaging, promote economical and clean production, and advocate the use of environmentally friendly, degradable, Recyclable and recyclable packaging materials, the demand for healthy, safe and environmentally friendly products has become a new development trend. "Limits of Volatile Organic Compounds in Cigarette Rod and Packing Paper" clearly stipulates the VOC limit indicators and judgment rules in cigarette packs, which undoubtedly increases the pressure on cigarette pack printing companies, and puts pressure on cigarette tippin...
