Embodiment 1

[0051] Embodiment 1, the detection effect is as follows:

[0052]

[0053] It can be seen that the detection method for the ability to form waterproof fog on the surface of trademark paper proposed by the application can be carried out by placing the trademark paper in a constant temperature and humidity chamber under the condition that the humidity is 55%, and by sequentially increasing the position of the sample in the constant temperature and humidity phase. The temperature method is to obtain the lowest constant temperature and humidity box temperature for the formation of water mist on the brand paper, and use this minimum temperature in the constant temperature and humidity box to characterize and compare the ability of different brand papers to form water mist.

Embodiment 2

[0054] Example 2, using the method proposed in this application to test the water-proof and fog-forming ability of the entire label paper surface.

[0055] The first step is to paste the whole label paper on a piece of flat glass, with the printing side facing outward, and then cover it with cellophane, which is 20mm larger than the border around the outside of the sample, and seal the surrounding with tape so that the sample is tightly attached to the flat glass. The ambient temperature in the sample preparation room is controlled at 23-26°C, and the humidity is in the range of 50-58%. join image 3 .

[0056] In the second step, put the prepared sample into a constant temperature and humidity box at 90°C and a humidity of 55%. After placing it for 10 minutes, take it out of the constant temperature and humidity box. After 58% cooling for 1 minute, observe the formation of water mist on different parts of the label paper surface. After careful observation, it is found that ...

Embodiment 3

[0058] In Example 3, it was tested by the electric heating blower method, only the sample E obtained after the solidification of the varnish added with 2% wax powder did not form water mist, and the other samples all formed water mist.

[0059] Test with the method proposed in this application below:

[0060] The first step is to cut sample A, sample B, sample C, sample D and sample E into a size of 50×30mm, paste it on a piece of flat glass, with the varnish facing outward, and then cover it with cellophane, which is wider than the border around the outside of the sample Larger than 20mm, sealed with tape all around, so that the sample is tightly attached to the flat glass. The ambient temperature in the sample preparation room is controlled at 23-26°C, and the humidity is in the range of 50-58%. join figure 2 .

[0061] In the second step, put the prepared sample into a constant temperature and humidity box at 90°C and a humidity of 55%. After standing for 30 minutes, ta...

Abstract

The invention discloses a detection apparatus and method for water mist formation resistance of cigarette packaging label paper. The detection device comprises a mounting table and a label paper sample to be detected, a constant-temperature and constant-humidity box is mounted at one end of the mounting table, strip-shaped through grooves are symmetrically formed in the two sides of the top of the mounting table, two sets of threaded rods are jointly arranged at the two ends of the interior of each strip-shaped through groove, the outer sides of the two sets of threaded rods on one side are jointly provided with a first movable block in a threaded mode. Through cooperative use of first L-shaped plates, an auxiliary edge sealing assembly and a second movable block, after a detector seals four edges of glass paper with an adhesive tape, a driving device is controlled to drive the threaded rods to rotate, and the second movable block is forced to gradually move towards one end away from the constant-temperature and constant-humidity box; when the top of a second mounting plate passes through the position below the first L-shaped plates, the glass paper is extruded by second guide rollers on the inner sides of the first L-shaped plates, so that the glass paper is firmly fixed on the surface of plate glass by the adhesive tape, and the functionality of the detection apparatus is greatly improved.

Description

technical field [0001] The invention relates to the technical field of printing and packaging, in particular to equipment and a method for detecting the water-proof and fog-forming ability of cigarette packaging trademark paper. Background technique [0002] Cover a layer of plastic film on the outer surface of the cigarette package, which is made of polypropylene heat-shrinkable film, hereinafter referred to as cellophane, to improve the airtightness and aesthetics of the cigarette package. Almost all cigarette packages are covered with a layer of cellophane, but in a certain In an environment with high temperature and humidity, if the cellophane is damaged, water mist will easily form between the label paper of some cigarettes and the cellophane. If it is too large, it will easily lead to moldy cigarettes inside, causing consumers' resentment and complaints, and affecting the reputation of cigarette brands. [0003] At present, before carrying out the waterproof fog test ...
