The force is applied in the direction of the flute axis. B-flute was developed next and is much smaller. With reduced fiber in the packaging, a more rigid box is created with less solid waste going into landfills. Corrugated flutes come in various standard shapes or flute profiles (A, B, C, E, F, etc.). The inventors of corrugated fiberboard applied this same standard to paper when they put arches in the corrugated medium. 6 Available from the American National Standards Institute (ANSI), 25 W. 43rd St., 4th Floor, New York, NY 10036. Each of these materials are mentioned in greater detail below: For example, in a triple wall board, one layer of medium might be A-flute while the other two layers may be C-flute. Allow for the addition of new flute sizes in the future in an orderly way 4. “A” flute was the original corrugated flute and is the thickest flute … See all 55 items in product family. Mullen Burst Test standards dictate a minimum board weight for the corrugated material. The flute type is to be as specified. A flute was the original flute profile for corrugated board. B-flute offers excellent puncture and crush resistant properties, and consumes less warehouse space. 1.2 The performance of fiberboard boxes is largely dependent on the paper components from which they are fabricated and, in the case of corrugated boxes, on the flute structure as well. Flutes per Linear Foot: 33 Thickness: 1/4".  Flute R Thickness 1.8mm to 2.3mm  Laydown boxe s to be specified and manufactured using a ‘C’ flute board grade. What does 125K/B/125T mean?
