Abstract: The present invention provides a composition for forming a film and its resultant film which has a high level of adhesiveness to a substrate and has good gas barrier properties. The composition for forming a film is prepared by adding a silane coupling agent to an aqueous dispersion liquid in which a cellulose nanofiber is dispersed in an aqueous medium. In addition, the composition for forming a film is also prepared by blending an aqueous dispersion liquid (a) which contains a cellulose nanofiber and has a pH 4-9 with a hydrolysis liquid (b) which contains alkoxysilane hydrolysates and has a pH 2-4 by a weight ratio of “cellulose nanofiber”/“alkoxysilane (in terms of SiO2)” in the range from 0.1 to 5.
