Analytical method for rapidly evaluating barrier property of inner liner for cigarettes

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...

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
