History
In 1856 the first known corrugated material was patented for sweatband lining in top hats. During the following four decades, other forms of corrugated material were used as packaging material for glass and other products shipped in wooden crates. Then in 1894, the first corrugated printed box was made. However, by 1900 there was a nationwide network of railroads that made it possible to distribute products throughout the nation. At this point, corrugated containers were still not a recognized classification by which to ship goods. The term “contained” meant enclosed on all sides in wood. While corrugated lacked the stacking strength of wood it was more affordable, more readily available, lighter weight, more uniform in quality, and more adaptable to volume packing, sealing, and handling. It also offered cushioning and printability advantages. All of these characteristics were attractive to businessmen at that time who were eager to take advantage of nationwide distribution. The corrugated printed box was initially used for packaging glass and pottery containers. Later, the case enabled fruit and produce to be brought from the farm to the retailer without bruising, improving the return to the producers and opening up export markets.
What is Corrugated Cardboard?
Corrugated cardboard, sometimes just called corrugated, is a sturdy packaging material made of three layers of kraft paper. It’s named for the interior layer of wavy paper, also called the corrugated medium, which gives the cardboard its strength. During manufacturing, the inner sheet is put through the corrugation process to create flutes or stiff folds in the paper. The corrugated medium is then glued in between two sheets of kraft paper, which form the exterior liners. Thanks to the three-layer structure, corrugated cardboard is much stronger than regular cardboard.
What is a Corrugated Box?
Corrugated shipping boxes are made of sheets of corrugated cardboard. Stacks of corrugated cardboard are trimmed, scored, and folded to create cartons of all shapes and sizes. Glue is applied to corners and folds for even greater stability.
Benefits of Corrugated Boxes
Sandwiched between two pieces of cardboard, the ridged flutes of corrugated paper are designed to support a great deal of weight. Not only is this beneficial for shipping purposes, but it also plays an important part in supporting the weight of food in pizza boxes and corrugated cardboard takeout boxes.
This cardboard fluting construction also plays an integral role in protecting items during transportation and preventing damage. The curved arches created by these flutes make boards durable and resist pressure applied from any angle. The empty space located between the flutes and under the arches even provides cushioning, as well as insulation in the event of extreme temperature changes.
Types of Corrugated Cardboard
All corrugated cardboard has a layer of corrugated fluting and at least one liner. Fluting and liners can be combined in different layers to create different types. These are the common types of corrugated board used in packaging and shipping:
