The present invention provides a resin film free from acetic acid generated by hydrolysis with time owing to change of environment and having high transparency. The resin film comprising ethylene-vinyl acetate copolymer, which has an extracted acetic acid amount of not more than 200 ppm, the extracted acetic acid amount being an acetic acid amount obtained by allowing the resin film to stand for 100 hours under the conditions of temperature of 85° C. and relative humidity of 85% and thereafter heating water containing the resin film under boiling and reflux to extract acetic acid from the resin film.
