Quality stability testing method for tipping paper for cigarettes

Abstract

The invention discloses a quality stability testing method for tipping paper for cigarettes. The testing method includes the steps: (1) taking a sample to be tested, cutting the sample to be tested into the size of 0.5-1.5mm<2>, and balancing the sample to be tested for 20-25 hours under the conditions of 23+/-1 DEG C and the relative humidity of 50+/-2%; (2) placing the tipping paper sample intoa volumetric flask after constant temperature and humidity treatment in the step (1), adding dichloromethane according to the volume mass ratio of 15-25mL:1g, sequentially performing vibration for 25-35 minutes at the frequency of 100-200r/min, ultrasonic treatment for 15-25 minutes and standing for 5-15 minutes, taking upper extracting solution, filtering the upper extracting solution by a 0.45 micrometer organic phase filter membrane, and taking filtrate as an analysis sample; (3) analyzing the analysis sample by a gas chromatograph-mass spectrometer, retrieving a chromatogram by an NIST11 standard mass spectra library, performing qualitative analysis by matching degree higher than or equal to 80%, taking integral values of chromatographic peak area as qualitative results, and comparingdifferential substances in different samples. Change of easily separated substances inside the tipping paper can be tested and analyzed, and the quality stability of the tipping paper for the cigarettes is controlled.

Description

technical field [0001] The invention belongs to the technical field of cigarette tipping paper analysis, in particular to a method for testing the quality stability of cigarette tipping paper. Background technique [0002] Cigarette tipping paper is one of the main materials of cigarette products. It is a special paper for cigarettes manufactured through pre-press design, printing processing (or coating) and post-press processing, based on tipping base paper. Its function is The filter tip and the cigarette butt are assembled together. In cigarette production, the quality stability of cigarette tipping paper has a direct or indirect impact on ensuring the production and processing of cigarettes and improving the quality of cigarette products. [0003] In the production process of tipping paper for cigarettes, the composition and ratio of the pigments, binders and fillers in the ink used for printing are stable, but due to the differences in the printing environment temperat...

Problems solved by technology

At the same time, the material composition and content of the tipping paper change, which may lead to the precipitation of individual substances in the tipping paper when the environmental conditions such as temperature fluctuate, resulting in the adhesion of the printing surface of the indirect packaging paper of different cigarettes. Quality brings hidden dangers

[0004] At present, enterprises producing and using cigarette tipping paper use headspace-gas chromatography/mass spectrometry, high-performance liqu
