Do you know which resin is typically used for plastic inks? Natural dammar resin exhibits excellent adhesion to untreated plastic films. Inks made from it feature strong adhesion and good flow properties. This resin dissolves in mixed solvents such as ethyl acetate and toluene, remaining stable without precipitation or flocculation after dissolution, resulting in a clear and transparent color. Using it in ink formulation enhances surface gloss and smoothness, making printed materials appear more aesthetically pleasing.
