With corrugated, there are varying thicknesses such as single wall, double wall etc.. There are also different flute types such A, B, C, E and F. These different factors will determine how durable your carton will be. There are also two tests in the corrugated industry that determine strength. One is bursting strength which is reported in pounds. The second test is the Edge Crush Test ECT. It is measured in pounds per lineal inch of load bearing edge. This performance test is related to the stacking strength of a carton. The ECT test measures the edgewise compressive strength of the corrugated and is reported as 32 ECT or 44 ECT etc.

Arches between the corrugated medium are known as flutes. When flutes are anchored to the linerboard with a starch-based adhesive, they resist bending and pressure. They also serve as an insulator, providing some product protection from sudden temperature changes.
- A flute was the first to be developed and is the largest common flute size
- B flute was next and is much smaller
- C flute followed and is between A and B in size
- E flute is smaller than B
- F flute is the smallest
Some examples of flutes are shown in the pictures below.
