B-Flute,
the second flute size adopted by the corrugated industry, has lower arch heights
than A and more flutes per foot (50). This means that the medium contacts and
supports the liners at a greater number of points, providing a stiff, flat surface
for high quality printing and die cutting and with excellent crush resistant
properties. B-Flute is also preferred for high speed, automatic packing lines
and for pads, dividers, partitions and other forms of inner packing. Complex
die cuts and beverage trays are excellent applications for B-Flute as are can
cases, wrap-around blanks, glass-to-glass packs and slipsheets. B-Flute is generally
combined with light weight liners but can be used with heavier facings if the
need arises.
49 Flutes / Foot
good puncture resistance
less space consumed in warehouse
uses: canned goods, displays
A-Flute
A-Flute, the original flute, is the highest flute size, and therefore, when
combined with an inner and outer facing, is the thickest. With 36 flutes to
the foot, A-Flute makes the most of corrugated's cushioning and stacking properties
for fragile and delicate items. Because A-Flute offers excellent stiffness qualities
and short column crush resistance, it has application across a broad range of
customer uses.
36 Flutes / Foot
E-Flute
has the greatest number of flutes per foot at 94 which gives it the greatest
crush resistance and the flattest surface for high quality printing applications.
It reduces box size and saves storage space. Because of its thin profile and
excellent cushioning properties, E-Flute can often substitute for conventional
folding cartons or solid fiber containers. Examples of E-Flute applications
include boxes for cosmetics, fragile glass and ceramic items and delicate instruments.
Another growing end-use is for pizza boxes where the retailer wants a cost effective
container with good graphics and excellent product protetion.

Flutes is the wave shaped corrugating material, the most recognizable feature
of a corrugated sheet
" The "Flute" describes the structure of the wave shaped
cardboard material that makes up a board's corrugation."
Offers excellent crush resistance.

Very thin-offers largest number of flute per foot which allows it to have
very good crush resistant features.
