2. 6. Getting to grips with cartons : Interactions of carbonboard packages with an artificial finger

   Author : Daniel Eriksson; Christer Korin; Sören Östlund; Örebro universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cartonboard packaging; Packaging mechanics; Packaging deformation; Manual handling;

   Abstract : Packaging is an important part of most products in our modern world. It produces waste, but it also enables products to reach consumers safely and efficiently. Hence, the proper design of packaging is becoming increasingly important. Historically, cartonboard packages were designed for box compression strength. READ MORE

4. 7. Pulp strength enhancement by oxygen delignification

   Author : Claudia Esteves; Elisabet Brännvall; Olena Sevastyanova; Sören Östlund; Christine Chirat; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber charge; morphology; oxygen delignification; swellability; tensile properties; dragegenskaper; fiberladdningar; morfologi; svällningsförmåga; syrgasdelignifiering; Chemical Engineering; Kemiteknik;

   Abstract : Oxygen delignification is widely used in the pulp and paper industry as a part of delignification process between the kraft cook and bleaching. However, its potential has not been fully utilized. READ MORE

5. 8. Wood chips for kraft and sulfite pulping : evaluation of novel forest-industrial drum-chipping technology

   Author : Jessica Gard Timmerfors; Leif J. Jönsson; David Blomberg; Sören Östlund; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood chip; drum chipper; impregnation; pulping; sulfite process; kraft process; Scots pine; Norway spruce; heartwood; frozen wood; moisture content;

   Abstract : Wood chipping and the supply of high-quality wood chips are of critical importance for most forest-industrial processes. The quality of wood chips affects product yield, product quality, and processability. READ MORE

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

   Author : Magnus Gimåker; Lars Wågberg; Sören Östlund; Steven Keller; KTH; []
   Keywords : ;

   Abstract : 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. READ MORE

7. 10. Influence of inhomogeneities on the tensile and compressive mechanical properties of paperboard

   Author : Anton Hagman; Mikael Nygårds; Sören Östlund; Nils Hallbäck; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paperboard; Inhomogeneities; In-plane properties; Tension; Compression; Shear properties; Delamination; Hållfasthetslära; Solid Mechanics;

   Abstract : The in-plane properties of paperboard have always been of interest to paper scientists. Tensile properties are crucial when the board is fed through converting machines at high speeds. Compressive properties are essential in the later use. Inhomogeneities affect both the compressive and tensile properties. READ MORE
