An Insight about Corrugated Fiberboards

The corrugated fiberboard is a material that comprises of one or more flat line boards and a fluted corrugated sheet. Corrugators are used to manufacture the #corrugated #fiberboards. Far from that, the corrugated fiberboards are used to produce corrugated boxes as well as shipping containers.


The History of Corrugated Fiberboards


The corrugated fiberboards were first unveiled in the 19th century. A patent was then issued for corrugated paper in 1856 in England. After the patent was approved, the corrugated papers were then used as liners for tall hats. At the time, corrugated boxboards were not yet patented; nevertheless, the corrugated boxboards were used as shipping materials and later on a patent was issued in December 1871.


The patent for the corrugated cardboard boxes was issued to Albert Jones who resided in New York City by then. Albert Jones used the corrugated boxboards to wrap glass lantern chimneys and bottles. Since technology does evolve, G. Smyth came up with a #machine that was able to produce corrugated boards in a large scale manner in the year 1874. Oliver Long then improved on the design that G. Smyth had come up with thereby paving the way for corrugated boards that have liner sheets on both ends.


Properties of Corrugated Fiberboards


The following characteristics and properties are measured when it comes to corrugated fiberboards;


• Flat crush test

• Edge crush test

• Impact resistance

• Bending resistance

• Tear resistance

• Shock absorption

• Burst strength


How Corrugated Fiberboards are manufactured


Corrugated fiberboards are manufactured through the use of machines known as corrugators that always operate at a frequency of 150 meters per minute/ 500 feet per minute. The corrugators have been experiencing #technological advancements over the years so as to increase the efficiency during the production process. With that said, the corrugated fiberboards are manufactured using papers, of which each layer requires a different grade of paper. Paper mills are in charge of producing the papers that are used in the manufacture of the corrugated boxes. During the corrugated fiberboard manufacture process, the papers are softened through the use of high-pressure steam. After the formation of the fiberboard, it is then dried and then heated afterwards through the use of hot plates. Flute patterns are also formed in the process, and they are then joined to a flat line board that has a starch-based adhesive, and the single-face board is formed. In the process, a second flat line board is also attached to the other end of the fluted medium, and a single wall corrugated board is formed. Among the common flute, sizes is the size “C.”


The Standard US Corrugated Flutes


The corrugated fiberboards can be classified by the construction specifics, the burst strength, flat crush, flute size, edge crush strength, surface treatments, test methods, and also coatings.


Corrugated BoxDesigns


Packaging engineers are always tasked with coming up with corrugated #cardboards #boxes that suit the various products that are being exported. The corrugated boxes are well designed in a manner that the will withstand various hazards such as vibration, moisture, shock, compression, and many more environmental hazards. Additionally, the packaging is also meant to suit the needs of the consumer and the retailers.


The most commonly used design is the RSC (Regular Slotted Container). Additionally, the boxes are always pre-orders, and they are manufactured depending on the specifics of the products that are to be fitted into the boxes.
