  1. 1. Mapping of Material & Conversion Parameters of Packaging Production – Boardio®

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Yusuf Qasem; Younes Chraibi Ottosson; [2022]
    Nyckelord :Chemical Engineering; Packaging; Packaging Production; Paperboard; Converting; Lamination; Extrusion; Die-cutting; X-ray tomography; GPI; Creasing; Perforation; Tensile Strength; Technology and Engineering;

    Sammanfattning : With an increased demand for sustainable packaging solutions for the ever-growing FMCG market, fiber-based systems rise as an answer to phasing out plastics in packages and reducing the humanity’s climate footprint. However, constructing a packaging solution largely consisting of paperboard comes with its challenges, such as integrating functionalities in the anisotropic paperboard that formerly were provided by a fundamentally different materials with divergent mechanical properties, being isotropic polymers.

  3. 2. Evaluation of the Scott bond method and testing of out-of-plane properties of paperboard

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Joel Olsson; [2022]
    Nyckelord :;

    Sammanfattning : The through-thickness mechanical behavior of paperboard is fundamental for converting operations and many end-use situations of paper-based products. High quality and uniformity of the through-thickness properties is ensured during paperboard manufacturing by use of on-line and laboratory quality control methods. LÄS MER

  4. 3. Enzymatic Modification of the Interaction Between Lignin and Recycled Cellulose Fibers

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Manfred Klug; [2019]
    Nyckelord :Lignin; Pulp and Paper; Recycling; Biotechnology; Enzyme technology; Laccases; Chemical Engineering; Kemiteknik; Technology and Engineering;

    Sammanfattning : The pulp and paper industry have been a growing market during the last decades. Due to higher environmental concerns among people, the recycling of papers has become an even more important part of the industry. Recycled paper fibers however are of lower quality than virgin fibers. LÄS MER

    Nyckelord :packaging; paperboard; paperboard roll; simulation; time saving; time efficiency; emballage; emballering; kartong; kartongrulle; simulering; tidsbesparing; tidseffektivisering;

    Sammanfattning : Stora Enso Skoghalls Bruk är en av de största kartongtillverkarna på vår planet. Var sjätte kartongförpackning i världen som innehåller något flytande kommer från Skoghalls Bruk. Kartong har liten påverkan på miljön då huvudråvaran, trä, är en naturlig råvara. LÄS MER

  7. 5. Micromechanical Investigation of the Effect of Refining on the Mechanical Properties of the Middle Ply of a Paperboard.

    Magister-uppsats, KTH/Hållfasthetslära (Inst.)

    Författare :Sofia Sandin; [2014]
    Nyckelord :Keywords: Refining; fibrillation; fines; SEM; 3D fiber network model; FE simulations; Malning; fibrillering; fines; SEM; 3D fibernätverksmodell; FE simuleringar;

    Sammanfattning : Optimized fiber utilization is crucial to the process efficiency and profitability in paper and board making. The fibers can be developed in a refining process in order to reach a desired quality level. LÄS MER
