Water based ink market analysis

Normal > Environmental characteristics of water-based ink

Normal > Water-based ink has two significant characteristics: First, low viscosity, good fluidity; Second, do not use organic solvents, which is conducive to environmental protection. The use of water-based inks reduces the emission of VOCs (organic volatiles) into the atmosphere, thereby preventing air pollution, improving the printing operation environment, and greatly reducing fire hazards. It can completely eliminate the harmful effects of certain toxic substances in solvent-based inks on the human body and the pollution of packaged goods, and improve the overall environmental quality. It is particularly suitable for packaging and printing products that require strict sanitary conditions such as foods and medicines.

Normal > Market Analysis of Water Based Ink    

Normal > At present, water-based ink is mainly used in flexo printing and gravure printing, and it occupies a considerable proportion in the fields of food packaging, tobacco and wine packaging, and children's toy packaging. In the United States, 95% of the flexographic printed matter, 80% of the gravure printing products, 40% of plastics using water-based inks are printed, the aqueous ink is more than twice the sales of solvent-based inks. In Europe, the proportion of offset inks has been declining year by year, while the proportion of water-based inks used for flexo printing and gravure printing has continued to rise.

Normal > Due to the late start of production and application of water-based inks in the country, most of the packaging and printing industry still use solvent-based inks. Water-based inks only account for about 7% of the entire packaging , but with the gradual progress of green packaging and environmental protection packaging. Popularity, tobacco, wine, food, beverages, medicines, children's toys and other hygienic requirements of packaging and printing products will gradually use flexographic printing, especially in the field of packaging and printing, the proportion of flexographic printing will gradually increase, so water-based ink The potential market in the country is huge. According to experts' predictions, by 2010 China's water-based ink consumption will account for 25%-30% of the total ink consumption , and annual demand for water-based ink will be more than 100,000 tons.

Normal > Water-based ink is particularly suitable for cigarette, wine, food, beverages, medicines, children's toys and other health requirements of strict packaging and printing products. Since the water-based ink does not contain volatile organic solvents, it can not only reduce the residual toxicity of the print surface, make the printing equipment easy to clean, but also reduce the risk of fire and hidden danger caused by static electricity and flammable solvents, so water-based ink is called new The "green" printed material.

Normal >   The pollution of the packaging to the environment and human body is mainly two aspects of packaging materials and packaging and printing. Direct contact with food packaging materials, such as paper, plastics, metals, etc. can not have any sources of pollution, but some materials are inevitable, we must rely on packaging and printing, to increase the protective layer on the substrate, so that food is not directly contact with a residual source of pollution Materials, such as printing or composite layers in plastic films, provide good barriers. However, this printing method involves hidden dangers, because in the traditional printing ink toluene is the main solvent (toluene content in the ink is usually 20% to 30%). In addition, the ink uses a volatile drying method. Therefore, toluene and other toxic gases in the solvent are directly discharged into the atmosphere to pollute the environment. After the printing is completed, there are residual toluene and other toxic substances on the surface of the substrate. Plastic films are mostly food packaging. Material, the presence of residues can cause food contamination. Water-based inks use solvents such as water and ethanol, which can greatly reduce the emissions of toxic and harmful gases. It will not cause any pollution to the substrate. From a food hygiene point of view, flexographic printing is the most suitable packaging and printing process; it is also the natural choice for pharmaceutical packaging. In some developed countries, regulations have even been established that must use flexographic printing to produce pharmaceutical packaging.
