Method for detecting lip sticking degree of tipping paper for cigarettes

Abstract

The invention relates to a method for detecting the lip sticking degree of tipping paper for cigarettes, and belongs to the technical field of analysis and detection. The method comprises the following steps: preparing artificial saliva of which the pH value is 5.5-7.5; transferring 20 [mu]L of artificial saliva, dripping the artificial saliva on a tipping paper printing surface with the area of more than 650mm < 2 >, then performing timing, and performing standing for a period of time; when the stipulated standing time is reached, absorbing excessive liquid on the printing surface of the tipping paper by using absorbent paper, and measuring the infiltration area of the tipping paper infiltrated by the artificial saliva; and judging the lip sticking degree of the tipping paper for the cigarette to be detected according to the artificial saliva infiltration area and the judgment standard. The method disclosed by the invention is rapid, simple, convenient and good in repeatability, can avoid subjective factor influence and difference characterization caused by traditional artificial sensory evaluation, greatly saves the detection cost, and has the advantages in material admission, quality control and product upgrading in the tobacco industry.

Description

technical field [0001] The invention belongs to the technical field of analysis and detection, and in particular relates to a method for detecting the sticking degree of tipping paper for cigarettes. Background technique [0002] Cigarette filter is mainly composed of three layers of acetate fiber, molding paper and tipping paper. Among them, tipping paper, also known as tipping paper, is used to wrap the outside of the filter and stick the filter to the end of the tobacco rod. Tipping paper is a kind of decorative paper obtained by printing, coating and other processing on the tipping base paper. It is usually cork color or opaque white, which can improve the appearance. The tipping paper is in direct contact with the lips of the smoker. Generally, only paint or ink is used for printing on the tipping paper. During the process, it dries slowly, and the remaining saliva protein on the lips will have a bonding effect on the tipping paper, causing the tipping paper on the fi...

Problems solved by technology

The utility model patent "a filter with anti-sticking lip and anti-pollution" is coated with a layer of protective film on the outside of the tipping paper and "a multi-functional tipping paper" with the purpose of anti-sticking lip, fragrance, flame retardant, etc., in the water The outer layer of pine paper is compounded with fruit flavor waterproof layer and protective film layer, but the judgment result of anti-sticking lip is not mentioned

There is no corresponding standard in the industry to regulate, and major companies only rely on the evaluation and judgment of professionals, which has great subjectivity and uncertainty. In order to determine whether different processes and types of tipping paper are sticky to lips / force, it is urgent to establish a corresponding objective screening method
