1. Numerical and experimental investigation of paperboard creasing and folding
Abstract : This licentiate thesis aims to increase the understanding of deformation and damage mechanisms of paperboard during converting, especially creasing and folding will be analyzed. A simple two dimensional creasing simulation was performed. READ MORE

2. Effects of plasticizing and crosslinking on coatings based on blends of starch-PVOH and starch-lignin
Abstract : A barrier material is usually needed on a fiber-based food package to protect the packed food from gases and moisture and thus maintain its quality. Barrier materials presently used in food packaging applications are mostly petroleum-based polymers. READ MORE

3. Continuum modeling of paperboard for the mechanical response of converting processes
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

4. Continuum modeling of the mechanical properties of 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

5. Impact of paperboard deformation and damage mechanisms on packaging performance
Abstract : Paper-based materials, such as paperboard, are commonly used as packaging materials. In addition to the fact that paper is renewable, there are also many other benefits of paperboard. READ MORE
