  1. 1. Critical Factors for digital Printing on Paperboard : Runnability, Functionality & Print Quality

    Författare :Veronica Gidlöf; Mittuniversitetet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital printing; paperboard; electrophotography; Other electrical engineering; electronics and photonics; Övrig elektroteknik; elektronik och fotonik;

    Sammanfattning : More than ten years ago, the first digital print units were introduced on the market and since then, the technology has developed rapidly. Digital printing on packaging material is, however, a rather new area, but a probable prediction is that there soon will be a market need for board products that can be used for digital printing.

  2. 2. Delamination of paperboard related to offset printing

    Författare :Orlando Girlanda; Christer Fellers; Fredrik Thuvander; Jeffrey Suhling; Karlstads universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Mechanical properties; Delamination; Finite Element Method; Paperboard; Z direction strength; Test equipment; Paperboard; Sheet Offset Printing; Web Offset printing; Shear stress; Modelling; Materials science; Teknisk materialvetenskap; Materialteknik; Materials Engineering;

    Sammanfattning : The relationship between the behavior of paper during converting operations and the mechanical properties of paper are a fundamental issue for both paper producers and converters. In the attempt to establish these relationships and thus be able to judge the performance of paper, several testing methods have been developed. LÄS MER

  3. 3. Continuum modeling of the mechanical properties of paperboard

    Författare :Eric Borgqvist; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; director vectors; polyconvexity; plastic spin; creasing; anisotropy; fiberous materials; Continuum Modeling; Paperboard;

    Sammanfattning : Continuum based elasto-plastic models for paperboard have been established in the work herein. The thesis begins with an introductory section that describes some of the background of the problem and gives some more motivation for the modeling choices made in the appended papers. LÄS MER

  4. 4. Influence of inhomogeneities on the tensile and compressive mechanical properties of paperboard

    Författare :Anton Hagman; Mikael Nygårds; Sören Östlund; Nils Hallbäck; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paperboard; Inhomogeneities; In-plane properties; Tension; Compression; Shear properties; Delamination; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : The in-plane properties of paperboard have always been of interest to paper scientists. Tensile properties are crucial when the board is fed through converting machines at high speeds. Compressive properties are essential in the later use. Inhomogeneities affect both the compressive and tensile properties. LÄS MER

  5. 5. Continuum modeling of the coupled transport of mass, energy, and momentum in paperboard

    Författare :Henrik Askfelt; Hållfasthetslära; []
    Nyckelord :Paperboard; Mixture theory; Porous media; Large strains;

    Sammanfattning : This thesis investigates the coupling between moisture, heat, and deformation in paperboard. The presented investigations are primarily conducted via macroscale continuum modeling but experimental characterisations are also made. LÄS MER
