  • Method for the preparation of NFC films on supports
    Publication number: 20180258244
    Abstract: The present invention concerns a method of preparing a film of nanofibrillated cellulose (NFC) on at least one surface of a support material, wherein the film is applied and spread directly onto a surface of the plastic support material in the form of a suspension of nanofibrillated cellulose, whereby the nanofibrillated cellulose forms a film. Further, the invention concerns a structure containing or consisting of a film of nanofibrillated cellulose prepared using said method.
