Flutes Used in Corrugated Cardboard

The flutes between layers of linerboard give strength and structure to cardboard boxes, and sometimes protective padding as well. They are shaped like arches, as this is the strongest formation when spanning a given space. These flutes resist bending and pressure from all directions for sturdier boxes and more creative options for sturdy but attractive point of purchase displays. 

Corrugated Cardboard Flute Types

Flutes come in several standard shapes or flute profiles (A, B, C, E, F, etc..). When the flutes are higher, they have steeper angles. The steeper the angles, the more strength there is in the box for stacking without crushing the flutes, thus maintaining the integrity of the box.
