Optimisation Stiffness of Paper and Board

Stiffness is important for almost all products of the paper and board industry. With a large number of Dutch paper and board mills, suppliers of measuring equipment and chemicals and Wageningen UR Paper and Board and the Competence Centre Paper and Board different research projects are carried out with the following aims:

• Detailed background information on stiffness requirements, stiffness properties and measuring techniques.

• Improvement of stiffness within the existing production process and by use of new raw materials and/or chemicals.

• Increased stiffness under humid conditions.

The research has been carried out in sub-projects, with different groups of participants, with general backup from the rest of the participating companies. Examples of sub-projects are:

• Optimisation of properties of laminate paper for optimised bending stiffness of multi-layer board

• Description and optimisation of stiffness requirements in the packaging chain

• Enhancement of stiffness, strength and roughness of grapic papers.

• Optimisation of starch efficiency

• Better use of measuring equipment for determining end product properties

For more information on this project, see also the presentation from the KCPK International Paper and Board conference (Beekbergen, The Netherlands, 6, 7 April 2004) or a short results overview (only in Dutch).
