Problems solved by technology

[0012] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide an analysis method for quickly evaluating the barrier performance of cigarette inner liner paper, which is different from the existing method of evaluating the barrier performance of cigarette inner liner paper by measuring the moisture permeability of samples. Method, the present invention provides an analysis method for judging the barrier performance of the cigarette lining paper by controlling the pressure value of the lining paper during the embossing process in the production process, measuring the air permeability of the lining paper sample under a certain test pressure, It is used to solve technical problems such as poor applicability, poor repeatability, poor accuracy and long measurement time of existing determination methods

Embodiment 1

[0069] 1. Sample preparation

[0070] Select three samples of cigarette lining paper: sample A, sample B, and sample C. Among them, samples A, B, and C are samples of different types of aluminum-free lining paper that are normally produced in the workshop and meet the standards.

[0071] 2. Measure the samples and record the results

[0072] Using a TQY500 paper air permeability measuring instrument, four different test pressures of 500Pa, 1000Pa, 1500Pa, and 2000Pa were selected to test the air permeability values ​​of the inner lining paper samples under different test pressures. The test range of air permeability is 0~40000CU, and the resolution is 0.5CU.

[0073] Divide the lining paper patterns A, B, and C into three parts, and number them respectively as paper patterns A1~3, B1~3, and C1~3. Among them, the paper samples A1, B1, and C1 are measured on the front side first and then on the back side, and the other paper samples are measured on the back side first and the...

[0081] 1. Sample preparation

[0082] Select two samples of cigarette lining paper: sample D and sample E. Among them, samples D and E are the normal production of the workshop and meet the standard lining paper samples. Among them, sample D is vacuum direct plating lining paper, and sample E is vacuum transfer aluminized lining paper. Embossing was performed on sample D, and the embossing pressure was set to 8 gradients (0, 1, 1.4, 2, 2.6, 3, 3.6, 4 Bar), and sample E was embossed, and the embossing pressure was set to 11 Gradients (2, 2.2, 2.4, 2.6, 2.8, 3, 3.2, 3.4, 3.6, 3.8, 4Bar).

[0083] 2. Measure samples, record results and analyze

[0084] Use TQY500 paper air permeability measuring instrument, select two different test pressures of 1000Pa and 2000Pa, test the air permeability flow value of the inner lining paper samples D and E, and draw the standard working curve.

Abstract

The invention provides the determination of embossing stress on inner liner for cigarettes as well as an analytical method for rapidly evaluating of a barrier property of the inner liner for cigarettes. The analytical method comprises the following steps: putting an inner liner sample for cigarettes into an embossing flow module of a hard package cigarette packaging machine, and setting the embossing stress for embossing; then putting into an air permeability tester for determining the air permeability, drawing a standard operation curve so as to obtain the standard range of the air permeability of the inner liner; and acquiring the actual born embossing stress of the sample, and comparing with the standard range of the air permeability of the sample, thereby determining the barrier property of the inner liner sample for cigarettes. According to the analytical method for rapidly evaluating the barrier property of the inner liner for cigarettes, the measurement time for the individual inner liner sample is less than or equal to 30s; the instrument stability is favorable; the analytical method is suitable for the cigarette enterprises adopting 7*24 hour all-weather production, is good in repeatability, has the variable coefficient less than + / -4%, is high in precision, is good in field production applicability, and can guide workshops to perform relevant quality control.

Description

technical field [0001] The invention relates to the technical field of analysis and testing of cigarette materials, in particular to an analysis method for quickly evaluating the barrier performance of inner lining paper for cigarettes. Background technique [0002] Cigarette lining paper is one of the important materials in cigarette packaging. It is a special paper used for cigarette inner packaging. It mainly plays the role of moisture-proof and fragrance-preserving. Plated lining paper, aluminum-free lining paper and various other new lining papers. For cigarettes, the inner lining paper for cigarettes must have good gas barrier properties, so that the tobacco and other substances in the package will not deteriorate due to oxidation, change taste, fragrance will not be lost, and odors will not be inhaled; at the same time, the inner lining paper for cigarettes It must have a good water vapor barrier, so that the tobacco and other substances in the package are not easy t...
