Folding Box Board (FBB) – also known as GC2 – comprises middle layers of mechanical pulp sandwiched between layers of bleached chemical pulp. The top layer, or liner, is usually white pigment coated in 2 or 3 layers. The reverse side is cream (manilla) as the back layer of chemical pulp is translucent allowing the colour of the middle layers to show through. The back layer of chemical pulp may be thicker and/or be white pigment coated, in which case the board is known as White Backed Folding Box Board (WBFBB) or GC1. FBB can also be plastic extrusion coated, laminated with materials such as aluminium foil and greaseproof paper and be given grease resistance (GRFBB) and other functional treatments.

FBB has a wide range of applications which include cosmetics, chocolate and confectionery, medical and healthcare, toiletries, dry foods, frozen and chilled foods, tea and coffee, biscuits, baked goods, clothing, toys, games and photographic products.
