We know now that boxes are made of corrugated paperboard, or simply “board” for short. There are several kinds of corrugated board, all made by combining paper, heat, adhesives, and pressure.

It starts off as rolls of liner or paperboard, similar in appearance to the brown paper in grocery bags. These rolls can weigh more than two tone each, and hold paper that cold stretch several miles.

Corrugated board can be made up of one, two, or even three layers of flutes and liners, depending on how strong the box needs to be.

There’s a box for practically every purpose, and building it begins when the box-plant salesperson asks the box-buying customer just what kind of box is needed, how many, and how soon?

Then a box designer starts planning. He or she has plenty to consider: the size and shape of the customer’s product, the size and shape the the finished box, the strength of the material it’s made of, the color of the corrugated board, the size of the flutes or paper ridges within it, the number of boxes to be made, the coatings and printing they’ll bear, and just when they’ll need to be made and shipped.  How will the customer put the box together, fill it, and close it? How will the customer’s customer open the box?  Will the product- filled box be moved by hand or by fork lift? Stacked in tall piles or singly? How roughly will it be treated?

Boxes are made at special factories called Box Plants. Corrugated boxes are designed to be very strong. They are made of corrugated paperboard, which is different from the stiff paper known as “cardboard.” Look at the edge of corrugated paperboard, and you will see a row of air columns. the air acts as a cushion, while the paper columns make the material strong. Each box is made to hold something just right, protect it from banging around, and keep it from spilling. Boxes are made with important information printed on them about what’s inside, or how to lift or move them. Carefully designed inserts hold items in place so they won’t spill or become damage.

Corrugated boxes are everywhere, caring products from all over the world and just down the hall. The pizza you eat probably comes in a brightly colored corrugated box. Your son or daughter, sister and brothers might even use a big corrugated washer, dryer or dishwasher box for a playhouse. You might flatten and collect corrugated boxes for recycling.
