Corrugated board is a material consisting of a fluted corrugated sheet and up to two flat linerboards. The fluted sheet and linerboards are then glued together to form corrugated board. This is made using special machines called corrugators and is essential in the process for making cardboard boxes. Corrugated board is sometimes referred to as corrugated fiberboard, corrugated cardboard and paperboard.
Originally developed as a packaging solution in 1871, corrugated board and the packaging industry as a whole has incurred incremental innovations over the last century, enabling corrugated board to have multiple uses and functions in the current day.
