What is Gravure Ink? Gravure (Rotogravure) inks are solvent-based ink with low viscosity, which can be quickly dried by vaporization. The advantages of gravure printing lie in the high, consistent, and continuously reproducible print result. Further, the benefit of fast-drying ink contributes to an immediate post-finishing of the printed goods. The ink is usually used in commercial printing of fle...

Resins are the carrier of the pigment in the ink, which is the core material of the ink. Along with pigments, resins convey important properties to the printing process as part of the ink vehicle. Resins impart many important characteristics of a finished ink, including gloss and adhesion, runnability on the press, and can also help disperse pigment.   The quality of the ink will directly aff...

Sunman’s CPP resin is a thermoplastic resin produced by the chlorination of polypropylene. It is a non-toxic white or light yellow granular solid and can be easily soluble in organic solvents such as chlorinated hydrocarbons, toluene, butanone or other mixed solvent. And it has high hardness and good properties of wear-resistance, acid-resistance, salt water resistance and aging- resistance. Chlor...

The major end-use application for flexible packaging is food packaging, which comprises more than half of the entire segment. This can only be expected to rise as more food categories and brand owners currently employing glass, metal or rigid plastics transition to the flexible packaging format. While the benefits of flexible packaging compared to other formats are well documented, one often overl...

1. Excellent yellowing resistance During the preparation process, polyurethane resin for printing ink is mainly synthesized from aliphatic polyester and aliphatic isocyanate as the main raw materials. Compared with aromatic polyurethane, it has excellent optical stability and excellent yellowing resistance after film formation. 2. Excellent adhesion fastness to film substrates The polyurethane res...
