Flutes give strength and structure to boxes,  serving as a protector, insulator and cushioning device. Our system is set up to automatically select the flute options that will function best for your box size and style.

E-flute is ideal for high-quality printing with a thickness of 1/16″. It is generally used for mailers and some special displays like beer and wine cases.

F-flute is half as thick as E-flute making it our lightest packaging option. Since this has the largest number of flutes per foot, it also allows for the most accurate folding operations. You’ll see F-flute offered in our smallest sizes.

B-flute is a good alternative to E-flute when wanting to support heavier items. With a thickness of 1/8″ and shorter flutes, this type of box still provides a rigid, flat surface for printing.

C-flute is commonly used for shippers. The flutes are taller here at 3/16″, giving C-flute somewhat better-cushioning properties than B-flute.
