What is Corrugated Cardboard?
Corrugated cardboard is cardboard that has been reinforced with more cardboard. Specifically, there are two parts to a corrugated cardboard box: linerboard and medium. The linerboard is the flat paper on the side; the medium is a more three-dimensional layer of wavy paper. Sometimes, as on single-face corrugated cardboard, there is only one side of linerboard, with the medium exposed. In single-wall (or double-wall, or more) corrugated cardboard, the medium is hidden in between two layers of linerboard, creating flat surfaces on both sides.
The image above shows the linerboard and medium of a single-wall sheet of corrugated, the most common combination used for shipping boxes.
Why Is This Great?
The wavy, fluted three-dimensionality of the medium provides a compact and lightweight layer of protection. Single-layer chip board (like the kind used for cereal boxes) isn’t usually used for shipping because it’s barely any protection at all, and shipping can be hazardous. A corrugated cardboard packing box provides much stronger protection against the elements (and against the wear and tear of travel and shipping) with the cushioned paper padding inside. It’s also better than plastic or wood because it’s lighter, far less expensive, and easier to recycle. Corrugated cardboard is therefore better for the environment and better for the pocketbook.
The flat linerboard, also being made of paper cardboard, is also an easier and less expensive surface onto which to print custom graphics. Custom print jobs are common on cardboard boxes for products that are shipped, stocked, stacked, sold, reused, repurposed, and recycled all over the world. (We’ve mentioned the importance of custom print for customers before.) The dual functionality of wavy inner layer for protection and flat outer layer for structure and printing make corrugated cardboard shipping boxes the ideal bridge between marketing and logistics for getting your product into the hands of your customers.
