One thing has not changed since 1902: our passion for corrugated board

We produce corrugated board, a natural product, and process it further. Corrugated board is a circular product, which means it is recyclable and can be reused after use. This makes it an extremely sustainable material.

Beginning of corrugated board: Albert Jones laid the foundation for today's corrugated board industry and applied for a patent for his invention - corrugated board - in the USA.

Corrugated board production and corrugated board processing

According to DIN 55468, corrugated board is cardboard made of one or more layers of corrugated paper, which is glued between several layers of another paper. A distinction is made between single-wall, double-wall and triple-wall corrugated board. The corrugated board is produced in several steps in a corrugated board plant. For the simplest form of corrugated board (single-sided corrugated board), two paper webs are used, the inner web and the flute. Three layers of paper are required for single-wall corrugated board: the cover sheet is visible from the outside, the corrugated material forms the corrugation and the inner sheet forms the inside of the packaging.
The most important raw material for corrugated board production is paper. Different requirements for the corrugated board packaging require different paper qualities, which are divided into kraftliner, testliner, and corrugated material.

In addition to the packaging-specific paper quality requirements, the paper quality of the outer web is also determined by the printing requirements. Simple uncoated paper qualities are suitable for good line prints and simple halftone prints. Halftone prints for demanding motifs can be realized with high-quality uncoated or coated paper qualities.

In addition to the use of paper, the choice of corrugated board types is also decisive for the technological values ​​of the corrugated board packaging, such as stack compression printing. The flute types differ fundamentally according to wave height and wave pitch and are classified into coarse, medium, fine and microwave as well as combinations for multiple flutes.
