Water-based inks can be applied to all plastic substrates. In principle, the printing package of high-temperature retort pouch can also be applied. The surface tension of the aqueous ink is matched with the surface of the substrate. The resin is the heart of the ink, which determines the base. The adhesion of the material. It is ideal for a surface of the substrate to reach 44 dyne. According to our tests, water-based inks have good adhesion on PET, PVC, BOPP and PE.

The quality of the product when printing water-based inks is directly related to the performance of the ink. At present, domestic water-based inks have better gloss than solvent-based inks; in terms of adhesion, adhesion on substrates such as PVC, PET, and pure aluminum foil is good.

Water-based inks are more complicated in the application process. Because water is used as a diluent, the surface tension of water is relatively large, and some surfactants are needed to adjust the tension, which involves the interaction between the additives and the ink properties.
