In the evolving world of flexible packaging and label printing, achieving vibrant metallic effects without compromising environmental standards has become a top priority. Aluminum paste, a specialized pigment blend made from finely milled aluminum flakes and dispersing agents, is now widely used in gravure and flexographic ink formulations to deliver superior visual impact and sustainable performance.

Aluminum paste offers exceptional optical reflectivity due to its platelet-like aluminum particles, which align within the ink film to reflect light uniformly. This alignment creates high-gloss, mirror-like effects, enhancing the luxury appeal of printed surfaces. Whether applied to PET films, BOPP, PVC, or coated paper, the result is a consistent and eye-catching metallic finish ideal for premium packaging in food, cosmetics, personal care, and electronics sectors.

Engineered for high-speed gravure and flexo printing systems, aluminum paste demonstrates excellent dispersibility and shear stability, ensuring smooth flow through doctor blades, printing cylinders, and anilox rollers. The paste integrates well with nitrocellulose (NC), polyurethane (PU), and polyamide-based resins, allowing for broad formulation flexibility without affecting viscosity, drying time, or print coverage.

Aluminum paste is highly versatile—it can be used as a standalone metallic silver ink or blended with CMYK pigments to create custom metallic shades such as champagne gold, rose silver, or sapphire blue. These custom blends are ideal for brand-specific color matching, enabling packaging designers to craft unique finishes that stand out on retail shelves and reinforce brand identity.

Meeting the increasing demand for sustainable solutions, modern aluminum pastes are now available in water-based systems, significantly reducing volatile organic compound (VOC) emissions compared to
