Abstract

The present invention relates to a method for treating a film comprising nanocellulose with an aqueous solution comprising tetraalkylammonium hydroxide, such as tetraethylammonium hydroxide and/or tetralkylammonium chloride, such as tetraethylammonium chloride or tetrabuthylammonium chloride to partly dissolve the film and to improve the barrier properties of the film. The invention also relates to a film produced according to the method and to a package comprising said film.
