1. Critical Factors for digital Printing on Paperboard : Runnability, Functionality & Print Quality
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. Delamination of paperboard related to offset printing
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. Continuum modeling of the mechanical properties of 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. Surface characterization methods for quality assessment of polyethylene-coated paperboard
Sammanfattning : 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. LÄS MER
5. Continuum modeling of paperboard for the mechanical response of converting processes
Sammanfattning : 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. LÄS MER
