Description
Technical Field
The invention belongs to the technical field of tipping paper detection, and particularly relates to a method for measuring the inter-paper mobility of saccharin sodium in tipping paper in a storage state.
Background
The tipping paper is an important auxiliary material for connecting the cigarette with the filter tip, and the saccharin sodium is added in the production of the tipping paper, so that the taste of the cigarette can be improved, and the quality of the cigarette can be improved.

Since the back surface of the tipping paper does not contact the lips of the consumer, sweetness cannot be generated, and the overall sweetness of the tipping paper is reduced. Moreover, the longer the tipping paper is stored, the greater the sweet taste impact on the tipping paper, which affects the overall inherent quality of the cigarette.
At present, the research on the detection of saccharin sodium at home and abroad mainly focuses on the content research in liquid and the relation research between an application process and sweet taste, and the related paper migration rate of saccharin sodium in tipping paper is not reported in related research.
