The Corrugated Box – The corrugated box has two main parts: the linerboard and the medium. Both of these components are constructed from a heavy paper known as containerboard.  The linerboard is the flat portion of the box which you can see that adheres to the medium. The medium is the wavy, fluted paper in between the liners.  The combination of the parts mentioned above create the corrugated box.

When a single sheet of corrugated is placed on its end, the flutes form rigid columns which can support a great deal of weight. The space in between the flutes acts as a cushion and insulation to protect the box’s contents.

Flute Sizes – Flutes come in many sizes and are determined by the distance from the bottom to the top of a single flute or the number of flutes per foot. Larger flute profiles deliver greater strength and cushioning.

Box Strength – When discussing box strength the first aspect to look at is wall density. Wall density is most commonly described as single, double, and triple wall. The more walls there are the stronger a box becomes. There are also numerous test by which a box is judged. The bursting test and the edge crush test are the standard used.

UPS recommends choosing a box strength that is suitable for its contents, based on the UPS Box Strength Guidelines. Never exceed the maximum gross weight limit for the box which is printed on the Box Maker’s Certificate on the bottom flap of most boxes.
