Folding Box Board

Incada Duo is a laminated folding box board product based entirely on fresh fibres. The individual layers in the laminate has a multi-layered fibre composition and construction designed to maximise its stiffness whilst having a low density. The outer layers consist of bleached chemical sulphate pulp, and the middle layers of thermo-mechanically separated fibres (TMP). Pigment coating can be applied to one or both sides, and its unique composition is designed to ensure that the product family meets different end-use printability requirements.

Product description

Incada Duo combines excellent stiffness with high-quality print performance and visual appeal, making it well suited for displays and other applications where both aesthetics and structural strength are important. The standard version is made through back-to-back pasting of Incada baseboard, creating two identical printing surfaces. Its fully coated surfaces ensure consistent print quality, while the high whiteness provides good contrast and vibrant colour reproduction.
