Corrugated cardboard is a highly ecological paper product composed of a corrugated layer and one or two layers of smooth paper. These products are widely used in the production of packaging and shipping containers.
Corrugated paper (folded paper) was patented in England in 1856, where it was used as inserts for tall hats. Corrugated cardboard was not patented or used as shipping material until 20 December 1871. A patent was issued to Albert Jones of New York City for two-ply corrugated cardboard. Jones used this corrugated cardboard for packaging bottles and for glass lantern chimneys. The first machine to mass produce corrugated cardboard was constructed in 1874 by a Mr. G. Smyth, with Oliver Long improving on Jones’s original machine to produce three-ply corrugated cardboard with smooth paper enclosing the central corrugated layer on both sides. He discovered the corrugated cardboard that remains in use today in the modern age.
Corrugated cardboard is characterised by 3 basic parameters: the number of corrugations, size of the corrugations and colour.
Types of corrugations and their characteristics:
|Types of corrugations||Number of corrugations
|A||108 +/− 10||4.8|
|B||154 +/− 10||3.2|
|C||128 +/− 10||4.0|
|E||295 +/− 13||1.6|
|F||420 +/− 13||
