Natural cardboard is not a specific type of cardboard that can be limited to the origin of the raw material, processing or colour. Natural cardboard is an umbrella term for folding boxboard with a natural, unbleached appearance, typically brown or grey and with a rough surface. Depending on the grade, natural cardboard often contains a high proportion of waste paper (secondary fibre) or a share of grass fibre, a rapidly renewable raw material. The term can be used to refer to grass cardboard, brown kraft cardboard and grey recycled cardboard, for example.
