Corrugated board can be produced in various thicknesses or heights. This is accomplished by shaping the inner paper of the board into any of several flute heights during the production, or corrugating, process. The higher the flute, the thicker the corrugated board. To designate the various flute heights, or board thickness, the corrugated paperboard industry applies letters and has derived designations such as A-flute, B-flute, C-flute, E-flute, and so on.

Most corrugated pizza cartons come in either B-flute or E-flute board. B-flute board is about 1/8-inch thick, E-flute is about 1/16-inch thick, or half as much. Some folks assume that B-flute, because it's thicker, comes with heavier paper, but that's not necessarily so. The flute size has nothing to do with paper thickness, or weight. The advantages of B-flute are that (a) it tends to warp less from pizza steam than does E-flute and (b) some folks believe that the thicker board connotes higher quality. The advantages of E-flute are that (a) it saves almost 50 percent in box blank storage space over B-flute and (2) it tends to print up slightly better.
