DUO TONE
Two-tone surface. One exceptional board.
DUO TONE is a premium kappa board engineered with a distinctive two-tone surface finish — one side bright white, the other natural grey. Designed for packaging converters and brand owners who demand visual contrast, superior printability, and consistent caliper in every sheet.
Engineered for contrast and performance
DUO TONE combines a bright white coated top surface with a natural grey reverse — giving packaging designers the flexibility to use both sides creatively. The white surface delivers excellent ink holdout and lamination adhesion, while the grey reverse provides a premium uncoated feel.
Manufactured at our Sivakasi facility using virgin and recycled fibre blends, DUO TONE boards are produced under strict caliper and moisture controls to ensure consistent performance on high-speed converting lines.
Available in a wide range of thicknesses and grammages, DUO TONE is the preferred choice for rigid box makers, premium retail packaging, and display board applications.
