Problems solved by technology

Cigarette wrapping paper will lose light, fade, and yellow after being exposed to natural climate conditions and light radiation for a period of time. Even indoor light or sunlight through window glass will affect it, not only affecting the overall packaging effect of cigarettes , it will even give consumers the illusion of fake cigarettes and lead to consumer complaints, thereby reducing the value of the packaged goods
[0003] However, there is no relatively scientific quantitative measurement standard for the evaluation of the light resistance of cigarette wrapping paper in the prior art, and it can only be carried out by experience or by using artificial light sources (xenon arc lamps) to simultaneously expose blue wool standard samples and cigarette wrapping paper. Comparative observation to determine its light resistance
Due to the influence of human factors and the insufficiency of the blue wool standard sample itself (printing and dyeing process), it is difficult to give an objective and stable judgment

Embodiment 1

[0021] The lightfastness properties of 10 kinds of cigarette packets were tested by using a spectrophotometer and a xenon arc lamp exposure box.

[0022] 1. Definition

[0023] 1.1 chromatic aberration

[0024] Refers to the difference between two colors, that is, the comprehensive difference of hue, saturation and brightness. It is represented by ΔE.

[0025] 1.2 light fastness

[0026] Hue change of the color of cigarette pack wrapping paper under the action of natural light source. It is generally expressed by the change of the color difference value, that is, the difference value obtained by subtracting the original color difference value before exposure from the color difference change value of the cigarette pack after exposure to the xenon arc light source for a certain time, temperature and number of times. The smaller the difference, the better the light resistance, and vice versa.

Embodiment 2

[0070] Example 1 was repeated with the following differences: 10 kinds of cigarette case wrappers were tested for their lightfastness performance. The size of the sample of the box wrapping paper: (50±10)mm × (50±10)mm.

[0071] The measurement results are shown in Table 2.

Abstract

The invention discloses a method for measuring the light resistance performance of cigarette wrapping paper. First use a spectrophotometer to measure the original color difference of the main color block of the cigarette wrapping paper to be tested, then place the sample in a preheated exposure box for 6 hours and then measure the color difference value after exposure, and finally use the cigarette wrapping paper The hue change (color difference value) before and after exposure to the sun is used to characterize the lightfastness of cigarette wrapping paper. This method is less affected by environmental and human factors, and the data is more objective and fair and can be quantified. The measurement time is short, which is beneficial to guide production. The repeatability and consistency of the determination results are superior to other test methods.

Description

technical field [0001] The invention belongs to the technical field of cigarette packaging materials, in particular to a method for quantitatively measuring the light resistance of cigarette packaging paper. Background technique [0002] It is very important to evaluate the lightfastness of cigarette case or small box wrapping paper. The light resistance of cigarette wrapping paper directly affects its use effect on packaging. Cigarette wrapping paper will lose its luster, fade, and yellow after being exposed to natural weather conditions and light radiation for a period of time. Even indoor light or sunlight through the window glass will have an impact, not only affecting the overall packaging effect of cigarettes , and even give consumers the illusion of fake cigarettes and lead to consumer complaints, thereby reducing the value of the packaged goods. [0003] However, there is currently no scientific quantitative determination standard for evaluating the light resistanc...
