Wax Additives for Water-Based Flexographic Inks

Water-based flexographic inks are increasingly used in packaging, particularly for sustainability-conscious brands. However, these inks can suffer from abrasion, scratching, and uneven surfaces during handling. Wax additives help maintain print quality and performance.

Advantages of Wax Additives

• Scratch Resistance: Micronized wax reduces surface abrasion during transport or cutting.

• Rub Resistance: Maintains printed image integrity in high-traffic applications.

• Improved Smoothness: Enhances ink leveling for consistent gloss.

Technical Insights

Carnauba wax emulsions and microcrystalline waxes are particularly effective in water-based systems. The optimal formulation ratio should be evaluated through compatibility testing for each specific ink system.

A packaging manufacturer incorporated a tailored wax blend into their water-based flexographic ink, resulting in fewer surface scratches and easier post-processing handling.
