The double-wall corrugated board can be bonded with single-faced corrugated board to produce triple-wall corrugated board. Triple wall corrugated board consists of seven paper webs: Outer liner, flute, intermediate liner, flute, intermediate liner, flute, inner liner.
The flute types can be combined in triple-wall corrugated board depending on the machine configuration. As with double-wall corrugated board, the larger flute type (AA) is inside because of the better cushioning properties. The medium flute (C) is on the outside because of the better protection against mechanical stress.
