Along with paying close attention to ensuring the quality of the finished product, Bobst Lyon designers have worked continuously to incorporate features which ensure ease of use and the highest possible productivity rates, especially if the boxes are destined for machine erection or are made from light weight papers.

Corrugated board

Corrugated board

Corrugated board is manufactured by combining lining paper with a fluting medium in a unit called a single facer. The liners used may be made from recycled, test, or kraft papers, and will consequently have a brown or white surface, which may be coated or semi-coated, depending on the application they are to be used for. Fluting medium is generally recycled paper.

In the single facer unit, heat, steam, and a corrugating roller are used to corrugate the fluting medium, which then has the liner attached. This creates single face, the basic building block of all corrugated board. Single face is used 'as is' for some specific applications such as litho-lamination, but is normally combined with further liners and fluting media to produce single wall corrugated (single face plus a top liner), double wall (single wall plus single face), or multi-wall (further combinations of the above).

The thickness of the corrugated material will depend on the fluting height created by the single facer and the combination of flutings used. The range of thicknesses can vary from 0,5 mm for the finest, up to 15 mm for the thickest, and sometimes more. The most commonly used grammages are in the range from 80 gsm to 300 gsm, however for some specific applications lighter or heavier papers may be used.
