Performance and market development of green ink (1)

in the past 10 years, China's ink industry has developed rapidly, especially in recent years, many enterprises have invested a lot of money in technological transformation and process transformation, the R & D and manufacturing level of ink have been continuously improved, and the use of new materials and new equipment has shortened the gap with the world's ink enterprises. At present, the production technology level and product quality of most ink enterprises in China have been substantially improved, and have been able to meet the quality requirements of domestic printing and packaging. China's ink production will continue to grow rapidly. According to incomplete statistics, China's ink production in 2003 has exceeded 300000 tons, ranking fourth in the world after the United States, Japan and Germany

with the continuous improvement of people's requirements for the quality of life and the survival and development environment, if the production temperature is too high, stretching will burn human body products. The packaging market calls for "green packaging materials", that is, to improve environmental protection performance, and choose public hazard free packaging materials that are energy-saving, low consumption, non-toxic, non polluting, and easy to degrade. "Green packaging materials" is the development trend of packaging and printing materials in the future, and people pay more and more attention to it. Printing ink is one of the more seriously polluted raw materials in packaging materials. "Green packaging materials" calls for environmental friendly ink products to meet the packaging requirements of high-end products

packaging ink, as an important growth field of global ink, and environmental friendly products are popular. Therefore, how to reduce the environmental pollution and energy consumption of ink has become the most important development direction of the ink industry

in China's flexible packaging printing industry, environmental friendly inks represented by water-based inks, alcohol soluble inks and UV inks are increasingly being ignored by printing manufacturers

specifically, in the flexographic printing market, ink has been developing rapidly in recent years and has a trend to catch up with solvent ink. It has advantages in ease of use and simple printing. Now, when the flexographic printing industry decides whether to choose ink or solvent ink, its confidence in ink has increased, making more printing work completed by water-based flexographic printing. At present, the performance that ink users require to improve is mainly in the following two aspects:

first, to obtain a ink system with stable pH value

the ink manufacturing industry must develop ink with stable pH value in the printing process, and there is no need to detect and adjust pH value in the printing process

second, improve re solubility

in the process of developing new chemical materials, fine chemical products and high molecular new materials industry in ink printing, with the volatilization of amine, the resin will gradually solidify, and even solidify in the printing form. According to the survey, ink manufacturers have improved the performance of the resin to make it easy to dissolve, which means that the printing system can run longer before cleaning, thereby increasing the printing output

I believe that with the mutual cooperation and joint efforts of relevant industries, that is, ink suppliers provide better ink, printing substrate suppliers provide film surface that is easier to combine with water, and printing machine manufacturers manufacture better drying equipment for water-based systems, the use of ink will continue to grow and make greater contributions to reducing VOC emissions

at present, volatile dry inks still occupy the mainstream position in terms of output and varieties of silk printing inks. However, the output of UV ink and water-based ink has increased year by year, and the increase is large. It is only a matter of time before its output exceeds that of volatile dry ink. In silk printing inks, UV inks and water-based printing inks have jointly occupied a large market

due to the increase in the types of oligomer, prepolymer and polymerization initiator in the raw materials of UV ink, the application scope of UV ink is wider, which is suitable for printing with various substrate materials, and its market share is bound to increase. At present, foreign water-based silk screen printing inks account for more than 50% of printing inks, because the surface of full-function water-based inks is dry for 5S and heat hardened for 10s; Ultrafine particle water-based ink can be printed with 500 meshes, 8 colors can be printed, and 6000 colors can be prepared by computer; The VOC content of water-based ink (cosmetic grade) is zero, and 50m2 can be printed per kilogram of water-based ink

in terms of composite film flexible packaging, after years of development, the production process of composite film has been relatively perfect, so there will be no major changes in the near future. Because gravure printing has the advantages of exquisite printing quality and high economy during long-term mass printing, it has been widely used in China. Due to the inherent characteristics of water-based ink, it can only be used in flexo and relief printing, and the high cost of UV ink also limits its application in gravure printing, Therefore, alcohol soluble ink with low VOC emission is the only product that meets the requirements of adhesives such as polyvinyl acetate latex or hot melt adhesive for environmental protection, and has a broad market prospect. Because the existing production process of composite ink is more or less accompanied by the production of waste, it is necessary to make some improvements in the production process to meet the needs of environmental protection. This is mainly reflected in:
