Kraton offers a wide range of non-reactive polyamide resins for packaging gravure inks, flexographic inks and cold seal release lacquers. The products can be divided into the following groups:
ALCOHOL SOLUBLE POLYAMIDES
These polyamides are designed to be soluble in ethanol or a blend of alcohols, and have very good ester tolerance. It is generally more compatible with nitrocellulose than the co-solvent or alcohol reducible types, and offer better low temperature gel resistance and recovery. The improved compatibility with nitrocellulose allows the formulation of printing inks with high heat resistance for heat-seal applications.
These polyamides are designed to be soluble in blends of alcohols or blends of alcohols and aliphatic hydrocarbon co-solvents. It can be formulated to give systems excellent adhesion, pigment wetting and gloss, fast solvent release, resistance to water, chemicals and deep freeze conditions.
RESINS FOR LAMINATING INKS
Designed to be soluble in a blend of alcohols, these resins provide prints with fast solvent release for low retained solvent and good adhesion to a variety of substrates used for flexible packaging.
