FEFCO: What is Corrugated?

What is Corrugated?

Corrugated is made from papers made up from cellulose fibers, which are virgin or recycled. This makes corrugated a renewable natural resource.

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 ingenious construction forms a series of connected arches which 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 which 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.

The 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.
