7 Technical Challenges and Breakthrough Solutions for Water-Based Ink Printing on PET Films
I. Adhesion Failure (Cross-Cut Test <3B) Failure Mechanism:Mismatch between PET surface energy (38–42mN/m) and water-based ink surface energy (45–50mN/m) leads to contact angle >65°. Solutions: Corona treatment: Dyne level increased to 54–56mN/m (power 8–10kW, speed 80m/min). Primer coating: Water-based polyesterurethane primer (dry film thickness 0.8–1.2μm).
