Do you know what the recognized environmentally friendly printing materials are?

The solvent of water-based ink is water, which significantly reduces the amount of organic solvent emission compared with general ink, prevents air pollution, is not easy to burn, has stable ink properties, bright colors, does not corrode the plate material, simple operation, low price, and adhesion after printing Good, strong water resistance, fast drying, especially suitable for packaging printed materials such as food, beverages, medicines, etc., and is recognized as an environmentally friendly printing material. Water-based inks are generally used for printing paper products and paper-plastic composite products. Although the solvent of water-based ink must be water, or mixed with a small amount of solvents such as alcohols.

The binders of water-based inks are all water-soluble resins or water-dispersible resins, which have a significant effect on the viscosity, adhesion, gloss, and adaptability of the dryer. Using rosin-modified maleic acid resin as a linking material to make printing inks can only be used for printing, and it cannot meet the gloss and water resistance requirements of medium and high-end packaging printing. Urethane resin has good stability, but printing adaptability and solubility are slightly poor. Styrene modified maleic acid resin, water-based amino resin, polyvinyl alcohol and carboxymethyl cellulose can also be used. The resin generally contains Hydrophilic groups such as carboxyl groups, hydroxyl groups, and amine groups can be used as binders for water-based inks.
