From the development of printing industry in developed areas of the future development track can be considered in China's packaging and printing industry to take the road of environmental protection is an inevitable trend, and the environmental protection of ink plays an increasingly important role.Although the stage has not yet established green ink or environmental protection ink discrimination standards, but the industry view is: those in the production and packaging and printing process less pollution, the health of human production and life and natural environment almost does not cause harm to the type of ink, it contains the following aspects of meaning. 1 significantly reduce the harmful components in the ink 2 significantly reduce the ink production and use of the process of the harm to the operator and the natural environment 3 It is beneficial to the recovery, treatment and reuse of packaging waste In accordance with the above standards, in line with the development of China's flexible packaging printing industry, at this stage in the market environmental protection ink is mainly the following many types: no benzene alcohol-soluble ink polyurethane ink water-based ink (acrylic acid system) UV light curing ink soybean ink single solvent ink. No benzene alcohol soluble ink: connection material for alcohol soluble polyamide resin, does not contain toluene, but contains a small amount of ketone solvents, more suitable for to be boiled flexible packaging printing, generally only for benzene soluble substitute plastic gravure table printing ink This kind of ink is no benzene packaging printing industry boom in the early launch of ordinary alcohol soluble plastic gravure printing ink. Acrylic water-based ink: big advantage is that do not contain volatile organic solvents, the natural environment no pollution, no damage to the ink maker and packaging printing operation technical personnel health, the deficiencies are ink film with poor gloss, packaging and printing drying speed is slow, packaging printing eligibility weaker, integrated the above a few factors, couldn't completely replace soluble acrylic type of water-based ink Agent ink. UV light curing ink :UV ink coating, UV light irradiation can be quickly dry curing, and the hardness of the ink layer is higher than other types of ink, with high environmental protection and energy saving solid content The advantages of low VOC content in high-speed inkjet printing and plate printing industry has great advantages, but in the flexible packaging gravure printing industry, compared with solvent ink,UV ink still has many deficiencies:First is UV ink price is relatively high, UV printing production line of the input is large, the demand is relatively harsh natural environment condition printing production workshop, this is also the UV printing ink is very difficult to mass in different packaging and printing industry to implement a major factors: second, UV ink in many printing substrate adhesion ...

Water-based plastic composite ink is a product with water as the solvent. From the perspective of printing mode, water-based ink is not suitable for offset printing at present. Its main application fields are flexographic printing gravure printing and screen printing. Printing costs are related to the raw materials selected by ink manufacturers, such as the size of the molecular weight of the resin formula production process, the addition of solvent in the printing process in addition to the closed printing workshop, the rest will change due to the temperature and wind and other factors. Water-based plastic composite ink to add diluent only as a reduction in the viscosity of the ink, so that it is suitable for printing, such as excessive adding, ink color concentration will be reduced, the amount of connecting material is reduced at the same time, so that it can not print a good product. Therefore, water-based ink only pure water, and is a one-time addition (pre-press) In the printing process, it will not cause color changes because of the change in viscosity, but not like ink, because of the waste generated when diluent needs to be added to the printing process, which greatly improves the qualified rate of printing products, saves the cost of solvent, reduce the emergence of waste this is one of the cost advantages of water-based ink.

In recent years, China's food packaging industry has developed rapidly, and the consumption of ink printing has increased significantly. With the continuous progress of China's industrialization in breadth and depth, various environmental and food safety problems have become prominent.The field of flexible packaging, especially as the food packaging industry involved in the estimated contact with food materials and products, has attracted social attention.Food safety accidents again and again touched people's sensitive nerve, in the food packaging food contact plastic products and printing ink glue drilling agent and other fields threw up a tide of banning benzene.Ecological environment protection is imperative, food quality and safety can not be ignored. Waterborne polyurethane series printing inks can be widely used in China's flexible packaging printing ink market, the key depends on some characteristics of waterborne polyurethane resin itself. 1.Compatibility of waterborne polyurethane resin: with waterborne polyurethane resin as the core, different auxiliary resins can be compatible, such as polyketone resin, phenolic resin, chlorine vinegar, tree vinegar, etc., and then the waterborne polyurethane printing ink system can be adjusted to show different characteristics, so as to be suitable for different application needs. The plasticity of waterborne polyurethane resin itself: waterborne polyurethane resin in the process of synthesis, according to the application of different raw materials to modify it, and then effectively guide the final product has the function that people need.
