What is the corrugated box

The design of the typical cardboard box is layered, utilizing a flat “liner” made of pressed paper pulp on both sides of a corrugated center layer. Sheets or rolls of pressed paper can be run through a machine to achieve the corrugated effect, by creating a fluted layer. Glue is added as the layers are bonded together. This process makes the material stronger and provides better padding for items placed inside the box.

A heavier design of the corrugated cardboard box is known as “double wall. This construction uses five layers instead of three as described above. Double wall cardboard includes a second inside liner as well as an additional corrugated layer.
