Fluting paper is used as a raw material in the manufacture of corrugated cardboard of various grades. Inner layers (corrugation) of corrugated cardboard are made from it.
The stable quality of packaging made of corrugated cardboard depends on the physics and mechanical characteristics of corrugated paper, as the corrugation takes the basic static and dynamic loads during transportation, storage, stacking of products packed inside the corrugated packaging.
