When looking at a corrugated (or cardboard) sheet, the arches are what is commonly referred as the flute. Flutes come in several common sizes or profiles: E, B, C, BC.

Combination of flutes are used to give more strength to the corrugated cardboard in compression and in flexion ( board BC for example).

As a general rule, if you plan to ship your products by courrier (FedEx, etc.) we recommend you Double wall courrugated cardboard
