How is corrugated made?
At its simplest, corrugated board is made from a combination of two sheets of paper called «liners» glued to a corrugated inner medium called fluting. These three layers of paper are assembled in a way which gives the overall structure a better strength than that of each distinct layer.
This type of board is called single wall corrugated board. Double wall and triple wall boards are also available in the market.
This ingenious construction forms a series of connected arches, a geometric form that is well known for its ability to support strong weights. This structure gives corrugated board considerable rigidity and resistance.The air circulating in the flutes also serves as an insulator which provides excellent protection against temperature variations.
History of corrugated
The history of corrugated dates back to almost 150 years ago.
Thanks to its basic raw materials, and despite considerable changes, modern corrugated packaging is not so different from that produced and used by our great grandfathers.
This ingenuous construction will always provide a very wide range of benefits and is and will remain popular, up-to-date and very creative.
