1. On the relation between paperboard properties and packaging performance
Sammanfattning : Paper-based materials, such as paperboard, are commonly used as packaging materials. Inaddition to the advantage that wood as a raw material is renewable, there are also many otherbenefits of paperboard. LÄS MER
2. Impact of paperboard deformation and damage mechanisms on packaging performance
Sammanfattning : 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. LÄS MER
3. Life Cycle Assessment of Paper Based Printed Circuits
Sammanfattning : Printed circuit boards have been massively manufactured and wildly used in all kinds of electronic devices during people’s daily life for more than thirty years since the last century. As a highly integrated device mainly consists of silicon base, an etched copper layer and other soldered components, massive production of printed circuit boards are considered to be environmentally unfriendly due to the wet chemical manufacturing mode and lack of recycling ability.

4. Design of Cellulose-based Materials by Supramolecular Assemblies
Sammanfattning : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

5. Determination of Weibull Parameters by Single Fibre Fragmentation for use in Modelling of Paper Tensile Properties
Sammanfattning : The thesis presents a method for characterization of pulp fibre tensile strength. Single Fibre Fragmentation (SFF) and Weibull statistics were used. Methods for specimen preparation, sampling and analysis of fragmentation data from digital images were developed. LÄS MER
