  1. 1. Identification of Fibers in Micro-CT Images of Paperboard Using Deep Learning

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :David Rydgård; [2023]
    Nyckelord :Fiber networks; Paperboard mechanics; Deep learning; Tomography; Image analysis; Technology and Engineering;

    Sammanfattning : This master thesis project explores the possibility of using deep learning to segment individual fibers in three-dimensional tomography images of paperboard fiber networks. We test a method which has previously been used to segment fibers in images of glass fiber reinforced polymers. LÄS MER

  3. 2. In-plane Wetting in Packaging Material and its Consequences for Cap Performance

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Ellinor Carolina Salomonsson; [2023]
    Nyckelord :Tetra Pak®; Aseptic; Paperboard; Pre-laminated hole; Edge wicking; In-plane wetting; Hydrogen peroxide; Cap detachment; Polymer technology; Technology and Engineering;

    Sammanfattning : Aseptic packaging solutions enable long time storage without refrigeration and are an important part of securing food supply globally. The package material consists of multiple layers: A paperboard for robustness, polymers for adhesion as well as shielding the board from liquid, and a barrier protecting the product. LÄS MER

  4. 3. Evaluating the pressure pulse in a flexographic printing press : Linking process parameters to specific pulse shapes

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Anton Hedström; [2023]
    Nyckelord :Flexography; printing; mottle; dot-gain; pressure; contact; Flexografi; tryck; flammighet; punktförstoring; tryckpuls; kontakt;

    Sammanfattning : In the printing industry quality is key, this is because a product is printed for a better appearance or to convey information. If the packaging for a product looks bad customers will get a bad first impression of the product. The quality of the print can be affected by many different factors. LÄS MER

  5. 4. Rate-dependent effects on the mechanical behaviour of paper

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Satyasarathi Poddar; [2023]
    Nyckelord :;

    Sammanfattning : It is established that paper properties depend on the loading rate. The rule of thumb is that the in-plane strength and stiffness increases about 10\%, when the strain rate increases by a factor of 10. Converting of paperboard into packages requires creasing of the paperboard followed by folding to make 3 dimensional packages. LÄS MER

  7. 5. Understanding The Impact Of Market demand For Paper And Paperboard On Swedish Ports : A scenario planning approach

    Magister-uppsats, Linnéuniversitetet/Institutionen för management (MAN)

    Författare :Hanna Persson; Dejan Bodiroga; [2023]
    Nyckelord :Paper; Paperboard; forest industry; bulk; container; cargo shipping; seaport; Port of Gothenburg; scenario planning; port investments; Papper; kartong; skogsindustrin; bulk; container; fraktsjöfart; hamn; Göteborgs hamn; scenarioplanering; hamninvesteringar;

    Sammanfattning : Background: The global marketplace is characterized by rapid and constantchange, resulting in complex logistics systems. The port industry, which is a crucial link in the supply chain, seeks to understand the complexity of market dynamics. LÄS MER
