METHOD FOR TREATING A NANOCELLULOSE FILM AND A FILM TREATED ACCORDING TO THE METHOD

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.

本发明涉及一种含纳米纤维素（nanocellulose）薄膜的处理方法：采用包含氢氧化四烷基铵（tetraalkylammonium hydroxide，例如氢氧化四乙基铵）和/或氯化四烷基铵（tetraalkylammonium chloride，例如氯化四乙基铵或氯化四丁基铵）的水溶液对该薄膜进行处理，以实现薄膜的部分溶解，并提升其阻隔性能。本发明还涉及依照该方法制备得到的薄膜，以及包含该薄膜的包装制品。
