Even if reading has gone a little out of fashion, paper is still in demand as a raw material. Paper is required not only for newspapers and books, but also for parcels, packaging, insulating material, bank notes, and furniture.
To avoid corrugated cardboard beds collapsing, to ensure packaging material provides safe protection, and so documents remain intact, paper and printed products must be stored and processed correctly.
Maximum precision and perfect humidity are required if newspapers are to be rattled off the rotary offset press at 55 km/h.
Paper is hygroscopic
Hygroscopic materials are substances that can trap moisture in their cell structure.
At low humidity, the air extracts moisture from the materials, often damaging the cell structure and causing cracks to form.
Cardboard packaging
For the production of packaging and packaging materials, ensuring a constantly precise humidity is an important parameter to guarantee the desired product and production quality: This applies in particular to the production and use of cardboard packaging. Even slight fluctuations in moisture content should be prevented here at all costs with regard to the end product. If the room humidity falls below the required optimum, the material releases moisture and the cardboard shrinks together (“curling”). Such shrinkage not only impairs the quality of the packaging, it can also lead to serious production problems in the printing process and during embossing.
