Anti-Blocking Wax Additives for Flexible Packaging Inks

Flexible packaging inks must retain their visual and functional quality throughout printing, lamination, and transport. Blocking — the unwanted sticking of printed surfaces — can lead to damage and waste. Wax additives effectively address this issue.

Advantages of Wax Additives

• Anti-Blocking: Reduces surface tack, preventing printed surfaces from sticking together.

• Slip Enhancement: Improves handling and runnability in high-speed printing and lamination.

• Scuff Resistance: Protects print quality during storage and distribution.

Technical Notes

Micronized polypropylene wax is commonly used for anti-blocking effects in flexible packaging inks, providing excellent slip without affecting overprintability. Formulation should be confirmed via substrate testing.

A snack packaging converter added an anti-blocking wax additive to their ink system, resulting in significant reductions in lamination defects and waste.
