  1. 1. Towards Paper Insulation Packaging: Evaluation of Thermal and Logistics Performance. A Case Study at HelloFresh

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Fernando Guardiola Ramírez; [2019]
    Nyckelord :thermal insulation packaging; paper-based; ice melt test; thermography; packaging scorecard; meal kit industry; Technology and Engineering; Agriculture and Food Sciences;

    Sammanfattning : The most common thermally insulated packaging used today is plastic-based and customer behavior towards plastic materials has changed rapidly in recent years. The Meal Kit Industry has a particular need for insulated packaging/cool pouch (CP) and is looking to shift from plastic materials to more paper-based ones. LÄS MER

  2. 2. Applicability of bio-based polymer packaging in the meal kit context - A case study with HelloFresh

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Theresa Stolberg; [2019]
    Nyckelord :bio-based polymer; bio-plastics; compostability; food packaging; sustainable packaging; Agriculture and Food Sciences; Technology and Engineering;

    Sammanfattning : Bio-based plastics are increasingly considered as sustainable alternatives to fossil-based plastics. Up until now, their application in the food packaging industry has been limited. LÄS MER

  3. 3. Mechanical and Thermal Characterisation of Novel UHMWPE Composites for Total Joint Arthroplasty

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Julian Somberg; [2019]
    Nyckelord :UHMWPE; Nanocomposites; DSC; Fracture Toughness; Wear;

    Sammanfattning : Total joint arthroplasty surgeries are known to have a high success rate but the longevity of the implants still acts as a limiting factor. Ultrahigh molecular weight polyethylene is the material of choice for the implant bearing surfaces due to its excellent clinical and tribological performance. LÄS MER

  4. 4. Predicting Mechanical Properties of Polymer Films after Extrusion Coating using Supervised Machine Learning Algorithms

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Sara Khayyami; [2019]
    Nyckelord :Machine Learning; Predicting Polymer Properties; Mechanical Properties; Stress – Strain; Processed Polymer; Extrusion Coating; Technology and Engineering;

    Sammanfattning : Tetra Pak is a world leader in providing innovative packaging solutions and processing technologies and has been so for a very long time. It is well – known that the material used for packaging purposes gets subjected to high temperature and pressure during folding and filling which could compromise the integrity of the material.

  5. 5. Thermomechanical characterisation of newly developed UHMWPE composites

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Petra Jan; [2019]
    Nyckelord :UHMWPE; nanocomposites; thermomechanical characterisation;

    Sammanfattning : Ultra high molecular weight polyethylene (UHMWPE) is a polymer commonly used in various applications, particularly in hip joint replacements. Despite its good performance, it is susceptible to oxidation degradation, which can be mitigated with the addition of vitamin E, and to excessive wear against metal countersurfaces, which can potentially be improved with the addition of nanoparticles.
