Alcohol-soluble or solvent-borne plastic flexo-printing ink is widely used by Current domestic industries. It is great harmful to the environment because of the harmful substances it contained. With today's increasing awareness of environmental protection, it is becoming the trend that green waterborne plastic flexo printing ink replaces solvent-based ink. By studying dispersion factors such as grinding resin, pigment/binder ratio and dispersant and testing print properties such as density, surface tension, glossiness and adhesion, water-based flexo ink formulation with good quality would obtain. Results showed that: by studying and testing print properties, water-based flexo ink formulates with good dispersion and adhesion, high color density and glossiness.
