  1. 16. 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.

  3. 17. Transient Dynamics and Core Tunneling in Vertical Spin-Vortex Pairs

    Master-uppsats, KTH/Nanostrukturfysik

    Författare :Milton Persson; [2019]
    Nyckelord :Spin-vortex; ultra fast vortex dynamics; milli-Kelvin temperatures; macroscopic quantum tunneling; Spinnvirvel; ultrasnabb virveldynamik; milli-Kelvin temperaturer; makroskopisk kvanttunnling;

    Sammanfattning : Spin-vortices in vertically spaced pairs of thin elliptical Permalloy nanoparticles are investigated. The two vortex cores with parallel out-of-plane magnetization exhibit a strong monopole-like attraction through the spacer much thinner than the core length, thus forming a bound core-core pair.

  4. 18. Investigation of graphene and nanocellulose hybrid films as a barrier material in packages

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Jens Bodelsson; [2019]
    Nyckelord :Nanocellulose; CNF; Graphene; Barrier; Dispersion; graphene nanosheets; coating; sonication; carboxymethylated; polymer technology; polymerteknologi; Technology and Engineering;

    Sammanfattning : In this report, hybrid films of carboxymethylated cellulose nanofibrils (CNF) and graphene nanosheets (GNs) have been prepared to evaluate if the GNs can enhance the barrier properties of the CNF films. CNF already possess great barrier properties at low relative humidity (RH) but it is drastically lowered when the RH reaches above 50% due to its strong hydrophilicity of CNF. LÄS MER

  5. 19. Recyclability by Design of Flexible Packaging

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Rafael Ferrándiz Martínez; [2018]
    Nyckelord :flexible packaging; recyclability; shelf-life; barrier film; structures; Technology and Engineering;

    Sammanfattning : This research has established a different approach towards a better design in packaging development for the Early Life Nutrition portfolio of Danone Nutricia Research. During this study, the value chain of plastic flexible packaging has been analysed by looking into the different technologies used at the sorting centres as well as technologies used to recycle multilayer films (e.

  7. 20. Proteinbaserat material för livsmedelsförpackningar : med fokus på mjölkproteiner

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Gabriella Apelthun; [2018]
    Nyckelord :Protein; whey; casein; edible films; food packaging; material;

    Sammanfattning : Livsmedelsförpackningar är ett område som har stor utvecklingspotential eftersom både konsumtionen och produktionen av plast har ökat sedan 50-talet. Trots att vi vet att konventionella plastmaterial framställs av råmaterialet petroleum, en icke förnybar och uttömbar källa. Förpackningsindustrin står för den största andelen plast. LÄS MER
