Folding Box Board

Incada is a folding box board (FBB) product based entirely on fresh fibres. It 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 Silk is a fully coated white-backed folding box board (FBB) designed for high quality packaging and graphics applications. The product has been developed and is produced to ensure a supremely smooth surface which is double coated with a unique and specially developed coating formulation. The reverse side of Incada Silk is single coated with a matt finish that provides consistent results in both solid print and halftone illustrations. This primary fibre paperboard consistently meets the requirements for high performance in quality printing and varnishing. The ink setting and drying properties ensure good runnability in high-speed offset litho processes. Incada Silk performs well in digital printing presses and is suitable for digital finishing technology.
