Cellulose based films as barrier material

 

PhD student

Malin From Nouryon

Description

The wood fiber contains the polymer cellulose (long molecular chain). If cellulose molecules are dissolved and regenerated the resulting film is quite similar to traditional plastic, but the raw material is bio based and renewable. The molecular chain can be modified with different side groups which will result in different properties in the regenerated film, for example can the material go from brittle to elastic, and from a material that acts as a gas membrane to one that can hold gas for a long time. With some modifications cellulose could most likely replace traditional plastic in the application it is used for today.

The objective of the PhD project is to understand how cellulose is dissolved and regenerated into films and how that influences the mechanical and barrier properties, it is also to know how to tailor cellulose molecules with different side groups to receive the desired properties of the films. What furthermore is interesting is how the properties alter with an elevated temperature, as not all traditional plastic are used in room temperature, so that will be included in the project as well. This will be achieved with small scale laboratory work to manufacture cellulose films and with small scale characterization at Mid Sweden University.

Development of strong and water resistant packaging materials from high yield pulps

 

PhD Student

Licentiate Tove Samuelsson MoRe Research Örnsköldsvik AB

Description

As paper materials are biologically degradable and wood fibre resources are renewable compared to plastics, there is no doubt that the change to paper based materials is important. This is the reason for making efforts in research and development, with the objective to optimize physical properties such as dry and wet strength of wood fibre based materials to match the expectations for packaging materials and bags. 

This work is focused on hot-pressing technique that has shown positive effects on strength properties for paper sheets based on lignin-rich pulp. The main issues in my study are fundamental aspects on the densification, comparing pulp qualities and optimizing conditions and materials.

Co-production

Company employs student finalizing with Licentiate exam. Contributes in courses and meetings with focus on mechanical pulp and papermaking processes, and on chemical and physical properties on paper based packaging materials.

Industrial adapted production of different types of nanocellulose materials optimized for increased strength for packaging- and printed paper

 

PhD Student

Licentiate Tommy Nordin MoRe Research Örnsköldsvik AB

Description

One of the potential applications of MFC, CNC and NFC in large volume is to use it as strength additives in paper and paperboard products that in most cases consist of mixtures of mechanical and chemical pulps. Nanocellulose can be used to improve the quality and performance of a broad array of paper and board materials, coatings and films, as well as nano-composite materials. MFC, CNC and NFC can be used as follows in papermaking applications; as strength additives, to enhance barrier properties in food packaging, to improved paper gloss, to reduce paper grammage and to enable smart packaging.

A major purpose of the project is to significantly lower the manufacturing costs and to facilitate the use of layer-by-layer technology by replacing the relatively expensive anionic component CMC (carboxymethylcellulose) with nanocellulose. To succeed, an industry-friendly system for cost-effective production of NFC (nanofibrillated cellulose), NLC (nanolignocellulose) and/or CNC (crystalline nanocellulose) must be developed. The idea of this project is to develop this type of system through optimization of fractionation and filtration systems where industrially available fine material fractions from pulp and paper manufacturing processes are tested.

ECF/TCF bleaching for the production of softwood tissue paper

PhD Student

Sara Starrsjö SCA R&D Centre

Description

It is well known that the bleachability of a certain bleaching stage depends on the prehistory of the pulp. It is assumed that this is due to the difference in composition and structure of the lignin and/or carbohydrates present in the pulp. However, the knowledge about which structures provides a good bleachability is limited. This work attempts to bring clarity to this field by examining softwood kraft pulps of different origins, in regards to charged structures.

When SCA during 2018 double the production of bleached softwood Kraft pulp at Östrand pulp mill, a new bleaching plant will be implemented, allowing for both ECF light and TCF bleaching. It is of great importance that these sequences are accurately optimized and understood, in order to minimize environmental impact, cost and assure high pulp quality.
