Wax Dispersions in Flexible Packaging Inks: Enhancing Abrasion and Block Resistance

Flexible packaging requires inks that are not only colorful and adherent but also resistant to friction, blocking, and chemical exposure. Wax dispersions—finely milled micronized waxes in water or solvent—play a vital role in upgrading these performance attributes.

1. Role of Wax Dispersions in Packaging Ink Performance
In high-speed printing (gravure, flexo), wax dispersions are added to water-based and solvent-based inks to achieve:

• Excellent Rub and Abrasion Resistance: Prevents smudging during transportation and shelf display.

• Improved Slip Properties: Reduces the friction coefficient, helping in smooth processing and packing.

• Anti-blocking: Prevents printed surfaces from sticking together under pressure or heat.

• Heat Resistance: Crucial for packaging exposed to elevated temperatures, such as during sealing.

2. Common Application Areas
Wax dispersions are widely used in:

• Food and Snack Packaging: Non-migratory grades ensure safety for indirect food contact.

• Pharmaceutical Packaging: Prevents ink damage during handling.

• Cosmetic and Personal Care Packs: Enhances premium feel and durability.

3. Wax Selection in Packaging Inks
Choosing the right wax dispersion depends on:

• Ink System Compatibility: Solvent or water-based.

• Printing Speed and Substrate Type: Plastic films, foils, or paper.

• Desired Surface Feel: Matte, semi-gloss, or gloss.
