  1. 1. 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

  3. 2. 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

  4. 3. The role of trial runs in manufacturing : A case study at a packaging company

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Anspach Emy; Jensen Johanna; [2022]
    Nyckelord :manufacturing; trial runs; packaging; strategy; product development; production;

    Sammanfattning : As the world puts increasing demands on sustainability, each organization has a responsibility to act, not only for its business to stay relevant but also for the world. It is possible to work towards sustainable development by replacing fossil-based materials with renewable and recyclable materials. LÄS MER

  5. 4. 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

  7. 5. A method for extracting delamination zones and deformation quantities of paperboard during folding

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Shan Langlais; [2019]
    Nyckelord :liquid paperboard package; continuum mechanics; optical flow; deformation gradient; strain; delamination; folding; image analysis; Mathematics and Statistics;

    Sammanfattning : Denna studie har genomförts på Tetra Pak för att studera deformation i vätskekartong under vikning. När en förpackning formas i fyllmaskinerna viks kartongen enligt biglinjerna. Det finns ett stort intresse av att studera vikprocessen då den är avgörande för den slutgiltiga kvaliteten av förpackningen. LÄS MER
