Linerboard is thick, rigid paper that is used to form the external faces of corrugated products and provide resistance to vertical loads.

Linerboard is offered in two lines:

  • Kraft linerboard (virgin fibre)
  • Natural brown or recycled white linerboard (recycled fibre)

As with the corrugating medium, linerboard qualities may vary depending on the desired use. These papers are also available in a range of thicknesses categorized by basis weights. The type of linerboard is chosen in accordance with the desired surface smoothness or final degree of rigidity.
