    Nyckelord :Kartong; Expancel Mikrosfärer; Bestrykning; Kompressibilitet; Viskositet;

    Sammanfattning : In Sweden, paperboard has been an essential product in the export market and is mainly used as packaging material. Packaging materials corresponded to 66% of all paper and board production in Sweden for the year 2020, which is an increase of 2,5% compared with the previous year [1]. LÄS MER

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

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    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.

  4. 13. Validation of An Iteration Free Material Model for Paperboard (NEO)

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

    Författare :Samuel Thomas Staines; [2022]
    Nyckelord :Paperboard; orthotropic; Constitutive equilibrium free; Non-linear; Curve fit constitutive relation; switch-wise history dependence; total formulation; explicit constitutive relation; In-plane; Elastic-plastic; Technology and Engineering;

    Sammanfattning : The NEO model, developed by Lindström (2019) for paperboard, is a non-linear material model that utilizes empirically based constitutive relations with switches to mimic elastic-plastic responses. Due to the explicit definition of the constitutive relations, the NEO model does not require a constitutive equilibrium loop. LÄS MER

  5. 14. Observation Based Modeling of Liquid Slosh in Drop Tests

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Victor Ekblad; Axl Roos; [2022]
    Nyckelord :Sloshing; Fluid Dynamics; Image Segmentation; 3D reconstruction; Machine Learning; U-Net; CNN; GCN; LSTM; Mathematics and Statistics;

    Sammanfattning : Tetra Pak® is a world leading food packaging company with a large variety of paperboard beverage packages. In the development of paperboard packages, an essential component is utilizing simulation models long before physical prototypes are manufactured. This speeds up the development process and allows quick evaluation of new designs. LÄS MER

  7. 15. 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
