Solid Bleached Board

Invercote is a multi-layered product (solid bleached board, SBB), entirely based on fresh fibres. Specific fibre compositions are used for the various layers in the construction to optimise performance. The outer layers are dominated by hardwood fibres to promote smoothness and printability. The middle layer consists of softwood fibres for strength and flexibility.

Product description

Invercote GL is a solid bleached board (SBB) which fulfils the need for very demanding packaging and high-end graphical applications. It is also suitable for aroma and flavour-sensitive products. Thanks to its composition of solid bleached primary fibres, Invercote GL has a superior strength and toughness and this strength gives several advantages in carton designing and processing. The printing side is triple coated which gives Invercote GL a smooth surface that is tailored to faithfully reproduce the most sophisticated printed images and the high demands of flawless foil and film lamination. The smooth surface allows for demanding printing in both traditional and digital printing. A patented coating formula provides outstanding lightfastness, giving the end products a longer life.
