Research and Development

Cellulose NanoFiber (CNF), a wood pulp-derived high performance material, is one-fifth the weight of steel but possesses five times its strength. It holds promise for applications in various fields, including automotive parts, films, filters, and paper. Various companies and research institutions are currently in a race to develop applications for CNF. Daio Paper is working to develop applications and overcome cost barriers toward commercialization of the new material.
