B-flute, E-flute, C-flute; what is the difference?
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 specialty displays like the beer and wine cases.
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.
