A method for manufacturing a film， wherein said film has a basis weight of less than 50 g/m 2 and wherein the density of the film is higher than 750 kg/m3 comprising the steps of: providing a suspension comprising microfibri Hated cellulose (MFC); forming a web of said suspension on a porous wire， microfibrillated cellulose (MFC); surface sizing said web， wherein the web， at the beginning of the surface sizing step， has a moisture content in the range of from 10 to 50 wt-%; drying said surface sized web to a final moisture content of between 0.1- 20 wt-% to form said film.
