Corrugated board is made from a combination of two sheets of paper called liners, glued to a corrugated inner sheet called fluting. These three layers of paper are assembled in a way that gives the overall structure a better strength than that of each distinct layer.
This ingenious construction forms a series of connected arches that are well known for their 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 that provides excellent protection against temperature variations.
There are many types of corrugated, each with different flute sizes and profiles which offer many combinations designed to create packaging with different characteristics and performances. Corrugated board is then cut and folded into an infinite variety of shape and sizes to become corrugated packaging. Corrugated is a high performance packaging material designed to pack, protect and promote products.
