Selective modification of fibres and paper yields new properties

Additives and auxiliaries are important constituents for selectively controlling fibre and paper properties. Strength values and optical properties must have long-term validity throughout the whole supply chain under all ambient conditions.

Ever greater demands are being placed on dimensional stability and moisture absorption, especially in the case of packaging and specialty paper – but in particular for graphic paper as well. This, however, is where classical dosing and additive combination reach their limits. Selective modification processes, integrated into the stock preparation of a paper or even chemical pulp mills, are able to achieve entirely new properties of fibres and paper.
