Cellulose films
Transparent cellulosic films as packaging or membranes are still niche products only. Our research focuses on the use of the Ioncell® technology to produce high-strength films through continuous extrusion. We are aiming at the development of a solid technical basis for further upscaling. Further, paths to functionalize films either through incorporation or derivatization are explored.
