  1. 1. Rate-dependent effects on the mechanical behaviour of paper

    University essay from KTH/Hållfasthetslära

    Author : Satyasarathi Poddar; [2023]
    Keywords : ;

    Abstract : It is established that paper properties depend on the loading rate. The rule of thumb is that the in-plane strength and stiffness increases about 10\%, when the strain rate increases by a factor of 10. Converting of paperboard into packages requires creasing of the paperboard followed by folding to make 3 dimensional packages. READ MORE

  3. 2. The “threat from abroad” and the breaking of the Swedish “cordon sanitaire” : A critical discourse analysis of right-wing party-political, online communication in Sweden

    University essay from Uppsala universitet/Medier och kommunikation

    Author : Hugo Ekström; [2022]
    Keywords : Radical right populism; immigration; criminality; political communication; Facebook; normalization; discursive shifts; moral panic; imaginaries; borderline discourse;

    Abstract : In the last decade, we have witnessed a new stage in the mainstreaming and normalization pro­cess of populist radical right policies and ideas in the Western world. This has resulted in in­creasing politicization of issues related to immigration. READ MORE

  4. 3. Mapping of Material & Conversion Parameters of Packaging Production – Boardio®

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Yusuf Qasem; Younes Chraibi Ottosson; [2022]
    Keywords : Chemical Engineering; Packaging; Packaging Production; Paperboard; Converting; Lamination; Extrusion; Die-cutting; X-ray tomography; GPI; Creasing; Perforation; Tensile Strength; Technology and Engineering;

    Abstract : With an increased demand for sustainable packaging solutions for the ever-growing FMCG market, fiber-based systems rise as an answer to phasing out plastics in packages and reducing the humanity’s climate footprint. However, constructing a packaging solution largely consisting of paperboard comes with its challenges, such as integrating functionalities in the anisotropic paperboard that formerly were provided by a fundamentally different materials with divergent mechanical properties, being isotropic polymers.

  5. 4. Continuum damage modeling of delamination in paperboard

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Author : Erik Jakobsson; [2021]
    Keywords : Creasing; Folding; MD-direction; EB material model; LS-Dyna; eGISSMO; Technology and Engineering;

    Abstract : This work concerns the creasing and folding of a continuum paperboard material model developed by Eric Borgqvist. Creasing is an operation that induces permanent deformation in the material, undertaken for the folding to be performed along a straight fold line without any in-plane cracks. READ MORE

  6. 5. Berlin's new rent cap bill : a controversy dividing the city?

    University essay from KTH/Urbana och regionala studier

    Author : Lisa Huesmann; [2020]
    Keywords : housing; housing policy; affordable housing; urbanisation;

    Abstract :   Urbanisation and growing populations are causing a lack of housing in many metropolitan areas such as Berlin, Germany. Especially tenants of rental units are affected by rapidly increasing housing prices that exhaust a growing share of their income. READ MORE
