Abstract: A method of manufacturing a film comprising microfibrillated cellulose,, wherein the method comprises the steps of: providing a first suspension comprising microfibrillated cellulose, having a dry content of from 0.2 to 2.0 %, wherein the first suspension has a first Schopper-Riegler (SR) value; forming a first web of said suspension; at least partly dewatering said first web; applying a second suspension comprising microfibrillated cellulose, and/or fines and/or fibers onto a surface of said formed and at least partially dried first web, wherein the second suspension has a second Schopper- Riegler value which is higher than said first Schopper-Riegler value, thereby forming a film.
