The corrugated paper products are composed of several layers of superimposed paper. These products made from virgin fibre or recycled paper are highly resistant. Some types of these materials are used to make packaging boxes and containers, of various types and sizes. Cardboard is also coloured, moulded and decorated. Hence, it depends on the applications for which it is intended. Additionally, adding thickness and volume to the cardboard is possible. Thus, you can support more weight through the intermediate layers of cardboard. Hence, without losing its shape and its usefulness.
How are the corrugated paper products made?
The boxes are economical to manufacture. It is therefore used both in packaging and the like. It is a widely used material in all parts of the world, and there are thousands of factories destined to its production. Also, it has the advantage of being recycled several times, due to its long and strong fibres.
The raw material
The pine trunk of the tree is the best to make cardboard. It is ideal due to its rapid growth and its ease of cutting and handling. With the small pieces cut, it is then crushed to prepare the fibre of the wood. Finally, the material is refined to convert it to paper.
A corrugated machine, called corrugator, is the one that produces the corrugations of the paper. After this process, several layers of paper are glued to the corrugated paper and pressed through an industrial process, to form the corrugated sheets. The union of these results in the carton.
What are the origins?
The origin of corrugated paper is during the nineteenth century and simplistic in origin. In a town in Brunswick, Maine, Colonel Andrew Dennison came up with corrugated cardboard for his son to pack his business jewellery and watches in Boston. Both invented a device that realised the cuts and slices of mechanical form. After that, this invention was improved to give definite shape to the corrugated paper, as we now know.
