The photo above is an extreme close up of B, C, E, and F flute corrugated board. The top two samples – B and C flute – are by far the most common for corrugated shipping containers, whether stock size boxes or custom made.
Functional Differences between B Flute and C Flute Corrugated
As you can see, C flutes are taller, giving C flute corrugated boxes somewhat better cushioning properties than B flute.
And because the flutes are shorter, B flute boxes offer a superior printing surface and more rigidity.
For most general purpose secondary packaging applications, B and C flute are functionally equivalent.
Sustainable Packaging Differences between B Flute and C Flute
B and C flute are constructed using equal amounts of linerboard. In this respect, there is no sustainable packaging advantage one way or the other.
However, because B flute is not as thick as C flute, B flute boxes consume less vertical space when being shipped to and stored by the user – about one third less space, as a matter of fact! This means –
Both of these points can have considerable environmental impact, since corrugated boxes are bulky and take up a good deal of space in a distributor or end user’s warehouse. Isn’t it amazing that something as small as a flute could have an impact on something as big as energy efficiency?
