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. The coating composition is adjusted in different general directions for the product family to satisfy printability requirements.

Product description

Invercote Creato is ideal for graphic design applications. It offers the same outstanding aesthetic printing properties on both the print and reverse sides. Both sides are fully coated and have a matt finish. The whiteness level is tailored to ensure the best print contrast and colour reproduction properties required for high-end print production. A patented coating formula provides outstanding lightfastness, giving the end products a longer life.

The range is further extended by Invercote Duo, available in grammages 450 –770 g/m².

Our mills and products are certified according to a number of standards, ISO and forestry. These standards are indicated on each specification sheet, as well as if they are compliant with application specific standards such as food contact, toy and archive.

Sheet grain direction

Grain results from the fact that fibers flowing onto the paper machine wire align themselves predominantly in the direction of their flow and the moving wire. The direction that is parallel to the flow of fibers on the wire is called the Machine Direction (MD). Direction perpendicular to the machine direction, or across the paper machine wire, is called the Cross Machine Direction (CD). Grain direction is called long-grain (or grain-long) when the longer sheet dimension is the same as, or parallel to, the machine direction. Shortgrain paperboard has its shorter sheet dimension parallel to machine direction. A diagram of each is below:
