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 Duo expands the creative possibilities due to its excellent printability and colour reproduction. It is made through back-to-back pasting of triple coated Invercote, which enables identical printing surfaces on the front and back.

Due to its strength, toughness and thickness, Invercote Duo is ideal for wines and spirits packaging, gift cards, different types of rigid exclusive packs and displays. It is particularly recommended for the packaging of aroma and flavour-sensitive products.

Invercote Duo can be extrusion coated to add barrier functions necessary under extreme conditions such as outdoor displays.
