Frequently Asked Questions

About Everything Corrugated

How do I Measure a Carton or Box?

The size of a corrugated cardboard box is always expressed by three dimensions: Length, Width and Depth (L x W x D). These measurements refer to the inside dimensions of the box. Inside dimensions should always be given in inches (1/16" fractions). The length is the larger dimension of the box's opening. The width is the smaller dimension. The depth is perpendicular to the opening.

What are "Flutes?"

Flutes are the waves or ripples on the corrugated medium. They can provide stacking strength or cushioning, depending on the direction and distance between them. There are three standard flute shapes: C – 41 flutes per foot and 11/64” in thickness. This is the most commonly used material. B – 49 flutes per foot and 1/8” in thickness. Good puncture resistance and less bulky than C flute. Good printing surface. E – 95 flutes per foot and 1/16” in thickness. Lightweight, excellent printing surface, easily folded, used for die-cut boxes and retail packaging.

What is "Dry Board?"

Dry board describes a condition where low humidity causes cracking in the board when it is folded.

What's a "Wall?"

Basically, a corrugated layer. The box is constructed from a board sheet comprising linerboard that adheres to the fluted or wavy medium to form the board. The two most common designs are:

• Single-wall – The corrugated medium is adhered to both an inside and an outside liner. The outside liner is generally smoother than the inside liner, which is more rippled. This is commonly used to construct boxes and other packaging components.

• Multi-wall (double/triple)– Consists of two liners with two or three corrugated media adhered between them. Again, the outer liner is smoother than the inner liner. Double- and triple-wall are used for packaging very heavy items or items that need ultimate protection.
