  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. Method development and screening of extractable organofluorine (EOF) and targeted PFAS analysis in food packaging materials

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

    Författare :Nora Larsson; [2022]
    Nyckelord :Per- and polyfluoroalkyl substances PFAS ; Food packaging materials; Extractable organofluorine; Method development; Combustion ion chromatography; Targeted analysis;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFAS) have been manufactured and used in differentapplications for several decades, including food packaging materials. During the last 20 yearsthese compounds have been acknowledged as hazardous for humans and the environment, anddifferent regulations on PFAS have been established on both national and international levels.

  4. 3. Aluminium water extract levels from liquid packaging board : A comparative trial study between alum and polyaluminium chloride added as flocculants on BM7, Stora Enso Skoghall Mill

    Master-uppsats, Karlstads universitet/Avdelningen för kemiteknik

    Författare :Hanna Cassel; [2022]
    Nyckelord :aluminium; alum; polyaluminium chloride; PAC; liquid packaging board; BfR; water extract; aluminium; alun; polyaluminiumklorid; PAC; vätskekartong; BfR; vattenextrakt;

    Sammanfattning : The aluminium content of water extracts is an important aspect for the food safety of paper board, as the content indicates the ability of the paper board material to transfer aluminium to the packaged food product. Aluminium intake in humans and its health effects have been discussed for many years as some research has seen potential links between, among other things, high aluminium levels in the brain and the development of hereditary Alzheimer's.

  5. 4. Identification and quantification ofmicrobiological risks in board production : A study of ATP bioluminescence and redox potential

    Master-uppsats, Karlstads universitet/Avdelningen för kemiteknik

    Författare :Claudia Bartos; [2022]
    Nyckelord :ATP bioluminescense; redox potential; bacillus; board production;

    Sammanfattning : Stora Enso is a well-established provider of renewable solution packaging and board materials.Board products for liquid packaging and folding cartons for food are particularly sensitive tothe microbiological contaminants. In the manufacturing process, microbiological growth occursdue to environmental favourable conditions. LÄS MER
