The structure formed by gluing one or
more sheets of fluted corrugating medium to one or more flat facings of
Paper used in forming the fluted portions of corrugated board.
Paper used for the flat outer facings of combined corrugated board.
Burst Strength -- The force required to rupture
corrugated fiberboard... measures puncture resistance.
Edge Crush Test (ECT) value -- The amount of force
needed to cause compressive failure of an on-edge specimen of corrugated
board... measures stacking strength.
Flute -- The wave shapes pressed into corrugated
medium. A, B, C, E and F are common flute types, along with a
variety of much larger flutes and smaller flutes.
