There are indications that the first notions of packaging goes back to the origins of mankind, about 500,000 years ago, in the time of the ancestral Pithecanthropus. They were designed initially for containing and transporting water and food, the first packages were made from elements found in nature, such as hollow horns, animal skulls and large shells.

In about 4000 BC, in ancient times, writing appeared. This started the exchange of goods between Mesopotamia and Egypt. The packaging, with containment concept for transportation, storage and commercial purposes, had its origin in this period. The products were packaged and shipped in bulk inside vessels. The containers were made from clay and natural fibers.

With the need to transport products over long distances, the appearance of the packaging changed. Around the year 3000 BC, the Egyptians began making glass bottles from molding sand. These containers were rustic, used to package oils, perfumes and cosmetics.

With the evolution in transportation methods and the intensification in trade, the need arose to protect the transported products, avoiding losses and contamination.

In 1856, two Englishmen, Healey and Allen obtained a patent for the first known use of corrugated cardboard: used in hat liners. The paper was fed, one at a time, in a simple hand operated machine made from two corrugated rolls.

Later, in 1871, the first use of corrugated cardboard for packaging appeared. The American, Albert L. Jones obtained a patent for wrapping fragile items like glass bottles.

Also in the United States, in 1874, Olivier Long patented the concept of attaching a flat sheet to corrugated paper, to strengthen it.

Since then, in 1881, some U.S. manufacturers concentrated their efforts on developing new machinery, because they believed that corrugated cardboard was a packaging new concept. Thus, the first motorized machine for manufacturing SINGLE-FACE cardboard emerged, which was quickly shown to the Europeans.

The first known corrugator was designed in 1895 by Jefferson T. Ferres, of the Sefton Manufacturing Co. This corrugated cardboard box had simple walls (cover, core, cover) was first used in 1930 by a cereal producer, who obtained official approval for this type of packaging for transportation.

The first corrugated cardboard factory was built in 1935 by João Costa and Ribeiro, who entered the Brazilian market with the corrugated single wall carton, hitherto imported from Germany.

The production of corrugated packaging showed a rapid growth, following the Industrial Revolution. In the 1940´s and 1950´s, with the emergence of the first supermarkets, the selling function of the packaging began to receive more emphasis. Visual aspects, such as shape and color, become increasingly important. Practicality of use, aesthetic appeal and functionality become fundamental requirements for the success, or failure, of a particular package.

Aware of the fundamental sense that the packaging has acquired over time, Celulose Irani offers a variety of products. Based on the singular needs of its customers, IRANI develops high quality customized solutions to meet their demands.

In doing so, with contemporaneity in its actions and transparency in its relationships, IRANI became nationally recognized in the corrugated packaging segment.
