Paperboard containing recovered fiber is a multi-ply material, formed in layers of recovered fiber.
Often grey in appearance, a white top layer made from recovered office paper is often used to provide a clean printing surface. Kraft padded mailers, Kraft bags, and wrapping paper made from OCC also fall under the packaging category. Cartons made from solid bleached sulfate or solid unbleached sulfate contain no or small percentages of postconsumer fiber, depending on the paperboard source.
