Sunman 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 polyamide
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.

Co-solvent polyamide

Co-solvent polyamide resin is also called Toluene soluble, Co-soluble polyamide resin or Benzene soluble polyamide resin. We can supply Toluene soluble Polyamide resin in different types, which main benefits its good stability, outstanding adhesion and water resistance, high gloss and excellent water and frozen crinkle resistance.

Untreated polyamide

It has excellent adhesion to untreated PE/PP, good pigment dispersion. It could be applied to printing ink which does not use nitrocellulose. M/w, it had outstanding adhesion to treated PE/PP and aluminum foil as well. as printing ink applied both to untreated and treated PE/PP, which has wide range of adaptability.
