Abstract

The invention provides a method for preparing cigarette tipping paper from waste tobacco rods. The tipping paper is made of tobacco stems, which are depilled and semi-fiber removed by wet method, and then sliced; then pre-rolled, pulp micro-ecological regulation and modified in order to collect fermentation broth and Tobacco rod fiber, the tobacco rod fiber is high-concentrated pulping and latent elimination treatment, and then it is classified by an upflow pressure sieve to obtain tobacco rod papermaking pulp, and the paper weight is 30-50g / m 2 , whiteness 40-80% (ISO), breaking length 1.5-3.5Km, elongation 1.0-3.0%, opacity 70-80% natural tobacco aroma paper base, add amino acid, reducing sugar and auxiliary The coating liquid is obtained by concentrating after the agent reacts, and the coating liquid is coated on the paper base to prepare cigarette tipping paper. The tipping paper can be used directly, promotes the development of the smoking material in the direction of green, environmental protection, sanitation, safety and resource utilization, and also has the functions of decoration and anti-counterfeiting.

Description

technical field [0001] The invention belongs to the technical field of paper used for cigarette tipping paper, and in particular relates to a method for preparing cigarette tipping paper from waste tobacco rods. Background technique [0002] With the improvement of people's living standards, the increasing awareness of health and environmental protection, people pay more and more attention to the problems of smoking and health. The appearance of cigarette packaging should not only be decent, pleasing to the eye, but also safe, hygienic, and environmentally friendly. There will inevitably be conflicts between the two. [0003] Cigarette tipping paper, also known as "tipping paper", is one of the important materials for surviving cigarettes. In recent years, the appearance design and processing technology of cigarette tipping paper have also become more and more innovative, and the raw materials and inks used are also emerging in an endless stream. Because in the cigarette s...
