Abstract
The present invention relates to a new process for improving runnability and dimensional stability when manufacturing a film comprising high amounts of microfibrillated cellulose (MFC) without negatively impacting the film properties. According to the present invention a high amount of nanoparticles is used as an additive, optionally together with a retention polymer.
