0010010 nbsp; 0010010 nbsp; In recent years, based on our experience in practical applications,Water-based varnishHas the following advantages:

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; (1) High transparency and good gloss. It has no adverse effect on the color of the printed matter. Even under the long-term strong sunlight, the coating film of the water-based varnish is not easy to yellow.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; (2) is not easily worn and scratch resistant. The surface of the printed object is not easy to wear, the color does not fall, and it is water and oil repellent, which is very popular and dependent on users. Use water-based varnish on cigarette cases. During high-speed operation at a speed higher than 300 ~ 500 packs / minute, the cigarette label should follow a large mechanical load, while water-based varnish can This requirement is better achieved, and no signs of discoloration of cigarette packets are found in either gravure or offset printing.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; (3) has no odor and is easy to use, transport and store. The water-based glazing oil uses water as a solvent, and only a small amount of edible edible ethanol is used as a co-solvent, which is conducive to safe production and improving the working conditions of employees. You can directly clean the equipment with water after finishing the light, there is no danger.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; (4) The conjunctiva is fast, the drying speed is relatively fast, and it can withstand high temperature and good heat sealing performance. The water-based glazing oil is applied on Heidelberg CD five-color continuous glazing offset printing machine. The printing speed is {{4}} sheets / hour, infrared drying, power {{5}}. 4 The kw × {{5}} branch × 2 group, with a temperature of 6 {{5}} ℃, has a good drying condition and has achieved satisfactory application capabilities. The cigarette pack uses PP film as the outer packaging, and the water-based varnish shows good heat sealing performance.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; (5) Good flatness and strong resistance to curling. The water-based glazing oil does not have too high a temperature requirement, and the use method on the gravure printing machine is more convenient than the general solvent-based glazing oil. A difficult problem in gravure printing is that after the printed matter is continuously dried in several color groups, the moisture content of the paper is relatively low, and the phenomenon of curling is more likely to occur, resulting in the product being unable to continue to use. The water-based glazing does not glaze the flexible packaging. The product is cut into large sheets, and then gilded and slitted. It still maintains good flatness and roll resistance. The user is very satisfied after use.
