Jonas Sundström Email jonas.sundstrom@ri.se Location Kista Ask me about Ask me about Service Shear strength profiles Out-of-plane shear properties are often very critical in paperboard. The out-of-plane shear strength is much weaker than the in-plane strength. Shear damage are therefore often causing failure. In the creasing operation paperboard… Service ZD testing In paper and paperboard the out-of-plane ZD properties are much lower than the in-plane properties. During end-use failure such as delimination is therfore common. In under to improve product performance it is therfore important t… Service Hygroexpansion Moisture-induced dimensional changes have a significant effect on the runnability of paper and paperboard in converting operations. This phenomenon of hygroexpansion is also largely responsible for web and reel defects such as cur… Expertise Press forming The need for sustainable packaging and single-use products is increasing in both the market and in the society. The need to utilize the resource efficient paper production and to form these 2-dimensional substrates into attractive…
