How corrugated board is made
Corrugated board is produced by combining various papers together in the form of paper layers. These layers are called liners and fluting (the fluting being formed to create a specific profile).
Each type of corrugated material will have different material layers in its construction:
- Single face (2 layers)
- Single wall (3 layers)
- Exposed flute (4 layers)
- Double wall (5 layers)
These liners and fluting once assembled give the overall structure better strength than that of each individual layer and as the fluting comprises of a series of connecting arches it is capable of supporting strong weights.
There are various types of corrugated, each with different flute sizes and profiles which offer many combinations designed to create packaging with different characteristics, strength and performances.
