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...

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...

Water based paint is often referred to as latex paint or acrylic latex paint. It contains a plastic resin that allows it to better adhere to walls. This and the paint pigments are suspended in water. Meanwhile, oil based paint consists of the particles of paint pigments suspended in an oil, which is typically linseed oil. Thus, the primary difference in composition is the added resin in water base...
