In the competitive world of printing and packaging, metallic effects can dramatically enhance product appeal and brand perception. Shandong Yinjian Aluminum Pigment Co., Ltd., with 38 years of specialized experience, delves into the critical factors for achieving optimal metallic performance in ink applications.

Understanding Aluminum Paste Fundamentals for Ink Systems

Aluminum pastes for inks require unique characteristics compared to coating applications. The key parameters include:

Particle Size Distribution

• Fine grades (5-15μm): Smooth, satin metallic effects

• Medium grades (10-25μm): Balanced sparkle and coverage

• Coarse grades (20-40μm): High sparkle for premium packaging

Leafing vs Non-Leafing Characteristics

• Leafing types: Excellent opacity, ideal for surface protection

• Non-leafing: Superior dispersion, better for process printing

Technical Challenges in Ink Formulations

Stability Issues
Aluminum pigments face compatibility challenges with various ink systems:

• pH sensitivity in water-based inks

• Reactivity with certain resin systems

• Settlement during storage

Printing Performance

• Viscosity control for different printing methods

• Adhesion to various substrates

• Rub resistance and durability requirements
