Board Types

Corrugated fiberboard, or combined board has two main components: the linerboard and the medium. Both are made of a special kind of heavy paper called containerboard. Linerboard is the flat facing that adheres to the medium. The medium is the wavy, fluted paper in between the liners.

	Single Face - one medium is glued to one flat sheet of linerboard.
	Single Wall - the medium is between two sheets of linerboard. Also known as Double Face.
	Double Wall - three sheets of linerboard with two mediums in between.
	Triple Wall - four sheets of linerboard with three mediums in between
