Embodiment 1

[0048] (1) Since the spot color yellow is the ink with the worst adhesion in the implementation case products, this embodiment selects the printing surface of the special yellow for adhesion testing. The spot color yellow used in this case is made by Hanghua UV offset printing ink and Limei The special yellow color prepared by special offset printing UV ink, the printing material is laser horizontal beam light column medium composite paper, take the test product sample and cut it into a sample with a length of 20cm and a width of 5cm for use.

[0049] (2) Paste the sample with 3M600 adhesive tape, pay attention to the smooth paste without leaving air bubbles, and pay attention to leave a small section at the other end for peeling test.

[0050] (3) The sample is rolled, the rolling speed is 400mm / M, the number of rolling is 3 times, and the length of each rolling is 150mm.

[0051] (4) Leave the sample after rolling for 5 minutes, and use a neutral pen to draw the outline of t...

Embodiment 2

[0056] (1) Since the spot color yellow is the ink with the worst adhesion in the implementation case products, this embodiment selects the printing surface of the spot color yellow for adhesion testing. The spot color yellow used in this case is the spot color yellow ink of Hanghua UV offset printing , the printing material is composite paper with laser stripe light column medium, take the test product sample and cut it into a sample with a length of 20cm and a width of 5cm for use.

[0057] (2) Paste the sample with 3M810 adhesive tape, pay attention to the smooth paste without leaving air bubbles, and pay attention to leave a small section at the other end for easy peeling.

[0058] (3) Roll the sample, the rolling speed is 200mm / M, the number of rolling times is 2 times, and the length of each rolling is 150mm.

[0059] (4) Leave the sample after rolling for 10 minutes, and use a neutral pen to draw the outline of the tape, so that it is convenient to use millimeter grid pa...

Abstract

The invention relates to a method for detecting an adhesive force of an offset ink of a laser cigarette case. The method comprises the following steps: sticking an adhesive tape to a to-be-detected ink printing surface of a sample; utilizing a peeling test machine for peeling the adhesive tape; coating a semitransparent millimeter ruling paper on the peeled part; respectively counting the number of grids occupied by an ink layer and that occupied by the peeled ink layer and calculating the adhesive force of the ink; judging if the adhesive force of the ink is qualified. The test method is simple and convenient; the test method is non-destructive; sampling and detection are only required following the production; the detection parameters can be adjusted and the magnitude of the adhesive force of the ink on the surface of the laser paper can be simulated according to the practical production condition; the detection for the adhesive force of the offset ink of the laser cigarette case ismore accurate, efficient and stable.

Description

technical field [0001] The invention relates to the technical field of laser paper cigarette packet printing quality detection technology, and more specifically relates to a method for detecting the adhesion of laser paper cigarette packet offset printing ink. Background technique [0002] Laser composite paper can not only improve the appearance and strength of paper and cardboard, but also mainly improve the performance of waterproof, moisture-proof, oil-proof, airtight and fragrance-proof, and also obtain heat-sealing properties, light-blocking properties, heat resistance, etc., so it It is a commonly used printing material for cigarette pack printing, but the surface energy of the surface layer of laser composite paper is generally relatively low, which may be lower than 4.O×10-2J / m2, and it is easy to cause poor ink adhesion during production. [0003] Ink adhesion refers to the force combined with physical and chemical forces when the ink and the printing medium are in...
