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

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

    Abstract : 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.

  4. 2. Delamination of paperboard related to offset printing

    Author : Orlando Girlanda; Christer Fellers; Fredrik Thuvander; Jeffrey Suhling; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Surface characterization methods for quality assessment of polyethylene-coated paperboard

    Author : Javier Mauricio Brugés; Jan Lundgren; Mattias Andersson; Mikael Sjödahl; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polarization; surface characterization; Stokes polarimeter; polyethylene coating; paperboard;

    Abstract : In manufacturing processes, the quality of a product often depends on its surface, and careful control of surface properties is critical to meet customer requirements. A thin layer of polyethylene (PE) is applied to paperboard to increase barrier functionality and high optical quality of the product. READ MORE

  7. 5. Continuum modeling of paperboard for the mechanical response of converting processes

    Author : Kristofer Robertsson; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paperboard; Continuum modeling; Converting processes; FEM simulations; Finite strain theory; Damage modeling; Rate-dependent; Creasing and folding; Out-of-plane experiments;

    Abstract : Paperboard is a thin and lightweight material made of cellulose fibers and it is an important component in packaging material where it provides stiffness and rigidity. The scope of this work is the development of continuum models, and its numerical treatments, for simulating the processes of converting paperboard into packages. READ MORE
