A method of producing a corrugated product comprises the steps of providing at least one medium conditioning apparatus upstream of at least one of a corrugating labyrinth, single-facer, and/or double-backer. The moisture content in at least one of a web of medium material, first face-sheet, and/or second face-sheet is adjusted to be in the range of 6-9 wt. % moisture by applying a substantially continuous thin film of liquid thereto using the at least one medium conditioning apparatus. In one example, at least one heating arrangement is arranged downstream from the at least one medium conditioning apparatus to heat at least one of the web of medium material, first-face sheet, and/or second face-sheet.
