Corrugated board production

Corrugated board is made from a combination of flat sheets of paper (called “liners”) glued to a crenulated corrugated inner medium (called “fluting”). These layers of paper are assembled to one another (typically using a starch glue) in a way which gives the overall structure a better strength.
Most commonly, a single layer of fluting is sandwiched between two liners. This type of construction, as shown in Figure 2, is known as single wall corrugated board.

Double wall and triple wall boards are also available on the market. A corrugated board grade called single face board consists of corrugated medium glued to only one flat liner (see Figure 3).

Various structures of corrugated fibreboard are illustrated below (after ISO 4046):
