Corrugated Paper Boards

What is corrugated paper?
Corrugated fiberboard is a paper-based material consisting of a fluted corrugated sheet and one or two flat linerboards. It is widely used in the manufacture of corrugated boxes and shipping containers.
Corrugated board is manufactured on large high-precision machinery lines called corrugators, usually running at 500 lineal feet per minute or faster. These machines over time have become very complex with the objective of avoiding some common problems in corrugated board production, such as warp and washboarding.

Cardboard Wall Construction

Cardboard Wall Construction
Although most people think that cardboard boxes have only one type of structure there are actually two different styles of wall structure that we offer to our customers. Depending on which characteristics and qualities you would like to have in your box, you can choose from single or double wall structure.



Single Wall Corrugated Cardboard
This is the most popular corrugation material used in the boxes we manufacture, it consists of only one layer of whichever type of flute you pick. It is available in a wide range of board strengths, from 23 ECT right throough to 44 ECT. Generally, depending on what type of flute you have chosen, this type of wall structure is not the best choice for shipping heavy objects.



Double Wall Corrugated Cardboard
This wall structure is made of one layer of “B” Flute and one layer of “C” Flute. Stronger than a single wall structure, double wall enables heavier objects to be shipped and should be used when a stronger box or extra padding is needed. Double wall is available in 48 ECT to 71 ECT and is excellent for stacking heavier items.
