2. 1. Laboratory method for the study of moisture-induced waviness in paper

   Author : Cecilia Land; Göran Ström; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; method; moisture; paper; paper web; wavelength; waviness; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

   Abstract : Paper that is subjected to moisture undergoes dimensional changes. It expands during moistening and shrinks during drying. When the paper is under tension between rollers, the effects are complex since shrinkage and expansion are restricted in the width direction. Waves can then appear on the paper web. READ MORE

4. 2. Mechanics of paper webs in printing press applications

   Author : Artem Kulachenko; Sören Östlund; Thomas Abrahamsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Travelling webs; skew tension profiles; mixed dynamic formulation; fluting; Other engineering mechanics; Övrig teknisk mekanik;

   Abstract : The mechanics of paper is a difficult subject because paper is a unique material. It is very thin, flexible at bending, unstable in compression and stiff at tension. Dealing with paper we have to account for orthotropy and heterogeneities created during the manufacturing process. READ MORE

5. 3. Strategies for improving kraftliner pulp properties

   Author : Stefan Antonsson; Mikael E. Lindström; Gunnar Henriksson; Mats Johansson; Hans Theliander; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignin; xylan; kraftliner pulp; mechano-sorptive creep; hygroexpansion; stiffness; fibre shape; fibre width; lignin; xylan; kraftlinermassa; mekanosorptivt kryp; hygroexpansion; styvhet; fiberform; fiberbredd; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Abstract : A large part of the world paper manufacturing consists of production of corrugated board components, kraftliner and fluting, that are used in many different types of corrugated boxes. Because these boxes are stored and transported, they are often subjected to changes in relative humidity. READ MORE

6. 4. Hybrid printing on fibre-based packaging : Performance, Quality and Market

   Author : Marcus Rehberger; Nils Enlund; Gunter Hübner; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; packaging; corrugated board; surface topography; print quality; variable data printing; hybrid printing; flexography; inkjet; print quality; market survey; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Abstract : Variable data will play a decisive role in the future of packaging and product promotion. Variable data printing (VDP) is a technique whereby certain information can be altered in an otherwise static layout with the help of a digital printing system, and in the packaging industry a wide range of applications is possible.

7. 5. Nonlinear Creep Model of Paper and Corrugated Board Materials

   Author : Poorvi Patel; Teknisk logistik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Finite element modeling; Creep-recovery tests; Schapery creep equation; Localbuckling; Orthotropic materials; Teknik;

   Abstract : Models of the nonlinear creep behavior of paper, and of the global buckling , local buckling and creep buckling of corrugated board have been developed. The studies of creep and buckling were limited to climate conditions with constant relative humidity. First the short-term elastic buckling of corrugated board panels was studied. READ MORE
