Corrugated cardboard is first of all classified on the basis of the number of corrugated layers. The boards are available with different flute types, e.g. C – B – E- F – W-Flute, defined by their flute width and flute height. The grades range from fine to large. In double-wall corrugated cardboards, it is possible to combine different flute types with each other: BC – EB – FE
The heavier the goods to be packed and the longer the transport distance, the greater the load the packaging must withstand (loading, climate, etc.).
It is one of the great advantages of corrugated cardboard that it allows for the combination of various different raw materials. By choosing the right paper grade and grammature, it is possible to produce corrugated cardboard products of a defined strength, which in turn determines the properties of the packaging.
