Fiberboard’s Organs<\/h2>\n

As we know, the human body is made up of many essential components, from the smallest microscopic cell to the largest of organs. The same goes for corrugated boxes, but instead of cells, there are tiny fibers, and instead of organs, there is inner fluting. All components are necessary to have strong and sound structure. Let’s take a look at the anatomy of a box.<\/p>\n

The Corrugated Fiberboard<\/h4>\n

What exactly is a box mostly made of? Corrugated fiberboard. The corrugated fiberboard is essentially the skeleton of the box. Made up by thousands of tiny fibers, it is created by a corrugator. A corrugator is a large machine that combines two different kinds of paper to create cut sheets of corrugated fiberboard. The flat, facing sheets are referred to as the linerboard. Linerboard is a\u00a0thin fiberboard that makes up the outer layer.\u00a0Flutes are inner arches attached in between the linerboards with a starch based adhesive. They are designed to resist pressure and bending in all directions.<\/p>\n
