Abstract: The present invention relates to a method for manufacturing at least one layer of a film wherein the method comprises the steps of:providing a first suspension comprising dialdehyde cellulose fibers with a first degree of oxidation;providing at least a second suspension comprising dialdehyde cellulose fibers with a second degree of oxidation which is lower than said first degree of oxidation;mixing the first suspension with the second suspension to form a mixture;mechanically treating the cellulose fibers in said mixture to microfibrillated dialdehyde cellulose;applying said mixture to a substrate to form a fibrous web; and drying said web to form at least one layer of said film.

Abstract: The present invention relates to a method for hydrophobizing a cellulose substrate, which comprises a first side and a second side, which faces away from the first side,wherein said method comprising the steps of:- drying the cellulose substrate (1) to a dry content above 80%, preferably above 85%;- providing a fatty acid halide in spray form;- converting said fatty acid halide in spray form into vaporized fatty acid halide; and- guiding said vaporized fatty acid halide to contact the first side of the cellulose substrate, and at least partially penetrate the cellulose substrate.

Abstract: The present invention relates to a method for measuring absorption of a substrate comprising a liquid barrier layer, said method comprising the steps of:a. providing a receptacle (3) arranged to receive a sample substrate (2), and a retaining arrangement (5) arranged to sealingly retain said sample (2) such that it sealingly separates the inside of said receptacle (3) from ambient air (6);b. adding a volume of matter (4) to said receptacle (3);c. providing a sample (2) comprising a liquid barrier layer (7);d. positioning said sample (2) so that the barrier is facing said receptacle (3); e. sealingly positioning said sample (2) so that said receptacle (3) becomes sealed;f. placing said sealed device (1) in a controlled environment/climate for a predetermined period of time; andg. removing the sample (2) from the device (1) and measure the amount of liquid absorbed during said time period.
