Poor adhesion of printing ink, which easily causes delamination and scratches, has long‑been a tough problem for packaging and label printing. Ketone‑Aldehyde Resin A81 serves as the key solution thanks to its excellent substrate‑bonding capacity.

Its molecular structure contains highly‑active functional groups that build strong binding force with ink resins and substrate surfaces. It can greatly improve ink adhesion on plastic substrates such as PET and PVC, metal foils and laminated paper. Meanwhile, it is compatible with multiple ink systems including solvent‑free and solvent‑based types without impairing ink gloss or drying speed, and fits mainstream printing techniques such as gravure and flexographic printing.

For scenarios with strict adhesion requirements like food‑grade packaging and electronic labels, Ketone‑Aldehyde Resin A81 can reliably prevent ink peeling and guarantee the durability and quality of printed goods.
