Technical Aid
Corrugated board is formed by gluing one or more sheets of fluted corrugating medium (the wavy paper in the middle) to one or more flat facings of linerboard. Common types of corrugated board are:
Single Face
Single Wall
Double Wall
Flute is a sheet of corrugating medium that is shaped into a continuous rolling wave. Well-known types of flutes include A, B, C, E, F flutes
| Flute Types | Corrugated Board thickness | Application |
|---|---|---|
| A-Flute | 0.3125"/8mm | Most widely used when structural strength is required. Not typically used for high graphics that are printed directly on to the board. |
| C-Flute | 0.1875"/ 5mm | Most widely used when structural strength is required. Not typically used for high graphics that are printed directly on to the board. |
| B-flute | 0.125"/ 3mm | Good print surface and strong structure |
| E-flute | 0.0625"/ 1.6mm | Excellent print surface that shows minimal flute lines or washboardings. |
| F-flute | 0.04"/ 1mm | Better printing than E-flute |
