Flexographic printing inks

Flexographic printing inks

We wish to produce flexographic printing inks for kraft paper. Could you please suggest suitable formulations?



Flexographic printng inks are often based on acrylic copolymer emulsions containing ammonia or an amine such as triethanolamine as solubilising agent. Lower alcohols such as isopropanol. as well as low boiling esters and ketones can also be used as co-solvents.

The collaidal state of the resin can be maintained with surfactants such as sodium stearate. Generelly speaking, the solids content of the end product is less than 30%.
Since you require these inks for application to kraft paper, it may be achisable to incorporate waxes, as for film and foil printing inks. These will collect near the surface.
