Manufacturing plant

Industrial line for the manufacture of corrugated board, with a capacity of 35,000 tons per year, with the ability to produce two-, three-, four-, five- and seven-ply corrugated board.

Corrugated board first appeared in England in 1856, where it was used as a base for making top hats. Charles Healey and Eduard Allen invented a hand-held machine with two ribbed rollers through which paper was passed to create corrugated paper.

It was first used as a packaging material in 1871, when Albert Jones patented a box composed of one flat and one corrugated layer of paper. A breakthrough was made in 1874 when Oliver Long added an additional flat layer to stabilize corrugated paper. This made corrugated board more suitable for protecting and wrapping irregularly shaped objects.

In 1881, George Smyth constructed the first mechanical machine for producing single-sided corrugated board, and in 1895, Jefferson T. Ferres created the first endless machine that enabled the manufacture of three-layer corrugated board (two flat layers + one corrugated layer). This product has become a standard in the protection and transportation of goods.

In Croatia, corrugated board production began in 1960. Until then, packaging was mostly made of wood, but given the advantages of paper – lower weight, easier transport and lower costs – the paper packaging industry developed rapidly.

Corrugated board is a packaging material composed of at least one flat and one corrugated layer of paper. Depending on the number of layers, its designs and purposes differ. Two-ply corrugated board, composed of a flat and corrugated layer, is flexible and used as a protective, lining or packaging material. Three-layer corrugated board, which has one corrugated and two flat layers, is most often used to make transport and commercial packaging. Five-layer corrugated board, with two corrugated and three flat layers, is stronger and suitable for packaging heavier products. The most durable is seven-layer corrugated board, created by adding an additional flat and corrugated layer to a five-layer structure. It is used for packaging very heavy, sensitive or dangerous goods such as machinery and explosives.

With the development of technology, corrugated board boxes are becoming increasingly advanced – they can be waterproof, antistatic, and moisture-resistant, and special designs are constantly being developed according to user needs.
