Everything you need to know about cardboard
Here at Reid Packaging we’ve done our fair share of high tech military and aerospace jobs. For example, we packed up two F-22 assembly plants for Lockheed Martin. But just because we’re packing up fighter jets, valuable tools and parts, and extremely fragile items doesn’t mean we’re above using cardboard.
Yes, that’s right, cardboard.
Or, corrugated fiberboard aka: “corrugated.” Whatever name you give it, we use lots of it to package and protect valuable items in shipping and storage.
Because it’s such a useful material across a wide variety of applications, we thought it would be nice to dedicate a blog post to this trusty stuff.
Cardboard or Corrugated Fiberboard?
When you think of a brown shipping box, you probably call the material cardboard. But because cardboard also refers to heavy-duty cardstock, cereal box material, and poster-board, we prefer a more specific term in the industry. We call it corrugated fiberboard.
Corrugated fiberboard is constructed using at least one sheet of thick paperboard and least one corrugated (rippled) sheet.
So all corrugated fiberboard will look a little like this from the edge. And it comes in a variety of thicknesses and configurations.
How is it made?
Corrugated fiberboard is made by combining an outside layer of thick paperboard and an inside, corrugated layer. The inside layer comes from a different kind of paper pulp that is thinner and ripples easily. It’s manufactured with corrugators – large machines that process the material at high speeds without warping. The corrugated layer, known as the medium, gets its rippled (or fluted) pattern from a combination of heat, moisture and a process that involves small wheels that form the ripples. It is then glued to the paperboard sides with a starch-based glue.
What are the different types?
Of course, corrugated fiberboard comes in a variety of thicknesses for different types of applications.
