VTT Technical Research Centre and Aalto University have developed a method which for the first time enables manufacturing of a wood-based and plastic-like material in large scale. The method enables industrial scale roll-to-roll production of nanofibrillated cellulose film. The film has very good oxygen and grease barrier properties and could also be suitable for e.g. food packaging to protect products from spoilage. The invention was implemented in the Naseva project (Tailoring of Nanocellulose Structures for Industrial Applications).
