  1. 1. Influence of fibre modification on moisture sorption and the mechanical properties of paper

    Författare :Magnus Gimåker; Lars Wågberg; Sören Östlund; Steven Keller; KTH; []
    Nyckelord :;

    Sammanfattning : Fibre modification might be a way to improve the performance of paper, to increase its cost competiveness and enable new paper-based products to be developed. Therefore, the influence of fibre modification (with polyelectrolytes or by fibre cross-linking) on the mechanical properties of special importance for packaging paper grades was studied. LÄS MER

  3. 2. Flexographic Post-Printing of Corrugated Board : Contact Mechanics and Print Quality

    Författare :Erik Hallberg Hofstrand; Magnus Lestelius; Peter Rättö; Astrid Odeberg Glasenapp; D. Steven Keller; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexography; Corrugated board; Post-printing; Contact mechanics; Print quality; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : As the corrugated board industry strives to produce products with a higher print quality in the converting stage, there is a need for a greater understanding of the factors influencing the final print quality and how we perceive the print. In this work, a method for quantifying the print quality of printed corrugated board is presented as well as methods that quantitatively characterize the mechanical interaction between the printing form and the corrugated board in the printing nip.
