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.

The soluble carrier of water-based plastic composite ink is water. Because water is used as the soluble carrier, water-based plastic composite ink has significant environmental protection and safety characteristics. It is safe, non-toxic, non-flammable and non-explosive, and almost no volatile organic gas is generated. No pollution to the atmosphere because of water-based plastic composite ink water as a solution carrier, so whether in its production process, or used for printing, almost no volatile organic gas to the atmosphere. Reduce print surface residual poisons to ensure food health and safety water-based plastic composite ink completely solves the toxicity problem of solvent-based ink, because it does not contain organic solvents, so that the print surface residual toxic substances are greatly reduced, this feature in tobacco, wine, food and beverage drugs Children's toys and other hygienic conditions require strict packaging and printing products reflect a good health and safety. Reduce resource consumption and reduce environmental protection costs due to the inherent characteristics of water-based plastic composite ink with higher isomorphic content, can be deposited in a thinner ink film, printing the same number and specifications of printed matter, water-based plastic composite ink consumption is reduced compared with solvent-based ink. To improve the safety of the working environment and ensure the operating personnel contact the health of the solvent in the manufacturing process and during printing ink is pretty dangerous, organic solvents and solvent ink itself is flammable liquid, organic solvent is quite volatile, can form explosive mixture gas in the air, after reaching concentration explosive limits in that Mars will explode Therefore, the risk of fire and explosion in the production environment is quite high, and the use of water-based plastic composite ink fundamentally avoids such risks. Anhui Sinograce Chemical Co., Ltd.(Sinograce Chemical) is mainly engaged in the business of chemical products,such as printing ink.Sinograce Chemical is mainly engaged in the business of screen printing ink and other product series.Good materials, advanced production technology, and fine manufacturing techniques are used in the production of chemical liquids. It is of fine workmanship and good quality and is well sold in the domestic market.

Water-based ink resin is the carrier of pigment in ink, is the core material of ink, its quality, will directly affect the performance of ink, because water-based ink resin to a large extent determines the viscosity of ink, dry fluidity and other properties.Anti - viscosity is an important physical property index of printing ink.Intaglio printing is a kind of printing with high order ink supply, good reproducibility and fast printing speed.After the ink plate transfer to the substrate, through the drying channel, to be fast volatile organic solvent drying that rewinding. As we all know, through high temperature drying after rewinding, printing film surface temperature is generally between 40 ~60, at the same time because of the existence of rewinding pressure, if the ink itself anti anti viscosity is not good, it will lead to serious rewinding adhesion quality accident, causing irreparable economic losses to ink customers In addition to the thoroughness of solvent gradient volatilization in the printing process, the anti-viscosity of ink is also directly related to the film formation and molecular properties of water-based ink resin.Good film forming water-based ink resin can give the ink good dry, in the solvent volatilization and thorough drying, film forming thoroughly, after winding anti anti viscosity excellent.

What is water-based adhesive Water-based adhesives are environmentally friendly adhesives made of natural or synthetic macromolecule as adhesives and water as solvent or dispersant instead of toxic organic solvents that pollute the environment.Existing water-based adhesives are not 100% solvent-free and may contain limited vocs as additives for their aqueous media in order to control viscosity or fluidity.Advantages are mainly non-toxic, pollution-free, non-burning, safe and easy to achieve clean production process, etc. Disadvantages include slow drying speed, poor water resistance and poor anti-freezing. The water based adhesive series has become a hot product of Sinograce Chemical.Sinograce Chemical's adhesive binder is commonly praised in the market due to good materials, fine workmanship, reliable quality, and favorable price.As for customer service management, Sinograce Chemical insists on combining standardized service with personalized service, so as to fulfill different needs of customers. This enables us to build a good corporate image.This is our email sales@sinogracechem.com, welcome to consult.
