  1. 16. 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

  3. 17. Temporal and spatial variations of microplastic concentrations in surface waters in Gothenburg, Sweden.

    Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :David Vigren; [2019]
    Nyckelord :;

    Sammanfattning : Temporal and spatial variations of microlitter (ML) concentrations in Gothenburg were measured by sampling surface water. ML was divided into three main categories; microplastics (MP), fibers (F) and other anthropogenic particles (OA). LÄS MER

  4. 18. Paper-based flexible laminates tendency to curl

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Clémentine Muller; [2018]
    Nyckelord :flexible laminates; paper; curl; relative humidity; temperature; Technology and Engineering; Agriculture and Food Sciences;

    Sammanfattning : The main purpose of this study is to assess the impact of environmental conditions on paper-based flexible laminates tendency to curl. Any deviation in flatness may indeed affect materials processability. LÄS MER

  5. 19. Chemical and physical changes in PET fibres due to exhaust dyeing : Issues in thermo-mechanical recycling of dyed PET textiles

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Frida Lindström; [2018]
    Nyckelord :Polyethylene terephthalate; polyester; exhaust dyeing; auxiliary chemicals; degradation; hydrolysis; thermo-mechanical recycling; fibre-to-fibre recycling; FTIR; DSC; tensile properties; demand absorbency test.;

    Sammanfattning : Polyethylene terephthalate (PET) is the most used fibre in the textile industry. PET is also used in other products, e.g. soft-drink bottles and food packaging. LÄS MER

  7. 20. Investigative study of Biopolymer contamination in conventional recycling systems

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Gauthaman Kuzhanthaivelu; [2018]
    Nyckelord :Biopolymer contamination; HDPE blends; PHA blends; PP; PET blends;

    Sammanfattning : The recycling industry which is efficiently functioning now has technical expertise, contented consumers, and resource availability and capital contributors. The potential inflow of new material into this existing system should be able to fulfill all the needs of the stakeholders involved in it. LÄS MER
