Corrugated has a ruffley layer, called “fluting,” between smooth sheets, called “liner.” Many types of corrugated are available, each with different flute sizes and thickness. The corrugated paper most commonly used to make boxes has one layer of fluting between two smooth sheets. Corrugated is made primarily from recycled corrugated and lumber industry byproducts, such as sawdust and wood chips.
Nowadays, one of the most frequently used raw materials for making corrugated is old corrugated. So the next time you see a corrugated box, you’ll know that it is recyclable, and that some of the fiber in it has probably been recycled once or twice already!
Corrugated fiberboard, or combined board, has two main components: the linerboard and the medium which is designated by the size of wave or flute. Both components are made of a special kind of heavy paper called containerboard. Linerboard is the flat facing that adheres to the medium. The medium is the wavy, fluted paper in between the liners.
A flat piece of corrugated fiberboard, which has been cut, slotted and scored is called a box blank. For some box styles, in order to make a box, the two ends of the box blank must be fastened together with tape, staples or glue. The place where these two ends meet is known as the manufacturer’s joint. Liquid adhesives are most often used to join two surfaces. Often there is a glue tab, extending along one end of the box blank.
This tab is scored and folded to form one corner of the box when joined. The tab can be joined to either the inside or the outside of the box. If there is no tab, the box must be joined using tape. Government regulations control the minimum size of the glue tab as well as specifications for the tape used and the distance between the staples. Most widely used box styles have a manufacturer’s joint.
