Flexible microfibrillated film formation

A method of manufacturing a film comprising microfibrillated cellulose, wherein the method comprises the steps of:

• providing a first suspension comprising microfibrillated cellulose in an amount of at least 50 weight % based on the total weight of solids of the suspension, 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 onto a surface of said formed and at least partially dewatered first web, wherein the second suspension has a second Schopper-Riegler value which is higher than said first Schopper-Riegler value;
• and,
• forming a film after the second suspension has been applied to said formed and at least partially dewatered first web.
