Description

As paper materials are biologically degradable and wood fibre resources are renewable compared to plastics, there is no doubt that the change to paper based materials is important. This is the reason for making efforts in research and development, with the objective to optimize physical properties such as dry and wet strength of wood fibre based materials to match the expectations for packaging materials and bags. 

This work is focused on hot-pressing technique that has shown positive effects on strength properties for paper sheets based on lignin-rich pulp. The main issues in my study are fundamental aspects on the densification, comparing pulp qualities and optimizing conditions and materials.

Co-production

Company employs student finalizing with Licentiate exam. Contributes in courses and meetings with focus on mechanical pulp and papermaking processes, and on chemical and physical properties on paper based packaging materials.

This project is financially supported by Kempe Foundation, MoRe Research Örnsköldsvik AB Sandvik Process Systems and the Swedish Knowledge Foundation, Mid Sweden University.
