    Sammanfattning : A world leading food processing and packaging company, Tetra Pak works with the vision of ‘Protect what’s good’ and aims to be a pioneer in developing sustainable packaging. Tetra Pak offers a wide range of carton packaging out of which aseptic carton packages are the most common. LÄS MER

  3. 22. The Investigation and Modeling of the interaction between Paperboard Clippings in a Pipe Flow

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Lea Christierson; [2021]
    Nyckelord :Fluid-structure interaction; paperboard material modeling; transient pipe flow; overset mesh; image analysis; Technology and Engineering;

    Sammanfattning : In the manufacturing process of Tetra Pak packages, holes are cut out of the paperboard for straws and caps. The left-over paperboard clippings, called confetti, need to be evacu- ated from the machine. However, this evacuation process has proven to cause problems due to jams arising as the confetti get stuck in joints and along the pipe walls. LÄS MER

  4. 23. Investigating the process parameters that influence the z-strength of liquid paperboard using data mining and machine learning

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

    Författare :Gustav Thaung Tolförs; [2021]
    Nyckelord :paperboard; liquid paperboard; z-strength; process parameters; machine learning; data mining;

    Sammanfattning : Parameters affecting the z-strength of liquid paperboard (LPB) has been analyzed and identifiedusing data mining and machine learning on 6 years of operational data from a multi-ply LPB mill, and control and stabilizing of them was proposed. Linear regression models were built for 9 articles with satisfactory results, and whose attributes were further analyzed as the most important parameters for the z-strength. LÄS MER

  5. 24. Continuum damage modeling of delamination in paperboard

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

    Författare :Erik Jakobsson; [2021]
    Nyckelord :Creasing; Folding; MD-direction; EB material model; LS-Dyna; eGISSMO; Technology and Engineering;

    Sammanfattning : This work concerns the creasing and folding of a continuum paperboard material model developed by Eric Borgqvist. Creasing is an operation that induces permanent deformation in the material, undertaken for the folding to be performed along a straight fold line without any in-plane cracks. LÄS MER

  7. 25. Evaluation of post-consumer recycled materials for folding cartons: A sustainable packaging study

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Nusara Intharakasedt; [2021]
    Nyckelord :Post-consumer recycled; folding carton; paperboard; consumer research; sustainable packaging; Technology and Engineering;

    Sammanfattning : Reducing the environmental impact from packaging has become a highlight in both consumers and industrial interest. The paperboard from virgin fibres is commonly used in the folding carton packaging across various type of products, including health care products. LÄS MER
