Corrugated Board

Corrugated board is made from a combination of two outer sheets of paper called liners, which are glued to the fluting or corrugated medium. The three layers of paper are assembled so as to give the overall structure a better strength than that of each separate layer.

The Fluting comes in varying thicknesses:

E FLUTE - approximately 1.8 mm thickness
B FLUTE - approximately 2.7 mm thickness
C FLUTE - approximately 3.7 mm thickness
TWIN CUSHION - a combination of two flute sizes, usually 'B' and 'C', is specified when high compression strength is more important

The Flute choice depends on the finished case's purpose and what it will carry. Charta can advise you on the best option for your packaging needs.
