1. New methods for evaluation of tissue creping and the importance of coating, paper and adhesion
Sammanfattning : The creping process and the conditions on the Yankee cylinder dryer are key factors in a tissue paper mill, and they therefore need to be kept under good control in order to maintain a high and uniform quality. To this end it would be valuable to be able to make on-line measurements of Yankee coating thickness as well as the crepe structure of the tissue paper. LÄS MER
2. Influence of Substrate Topography on Ink Distribution in Flexography
Sammanfattning : The printability of paper in flexography is largely dependent on the topographical characteristics of the substrate. Topography imaging instruments make it possible to obtain three-dimensional scans of paper surfaces that can be further used to calculate valuable quality parameters. LÄS MER
3. Aspects of Flexographic Print Quality and Relationship to some Printing Parameters
Sammanfattning : Flexographic printing is a common printing method in the packaging field. The printing method is characterized primarily by the flexible printing plate and the low viscosity inks which make it suitable for use on almost any substrate. LÄS MER
4. Properties of modified starches and their use in the surface treatment of paper
Sammanfattning : The papermaking industry uses a large amount of starch each year, both as a wet-end additive and as a rheological modifier in surface sizing and coating colors. It is important to be able to reduce the amount of chemicals used in the papermaking and surface treatment process, to reduce costs and to make the process even more efficient. LÄS MER
5. Influence of paper properties and polymer coatings on barrier properties of greaseproof paper
Sammanfattning : Greaseproof paper has a dense structure and therefore provides a natural barrier against materials like fat and oils. The barrier is obtained by extensive refining of the pulp. LÄS MER
