PROBLEM TO BE SOLVED: To provide an individual packaging film with the coefficient of dynamic friction of 1.0 or more excellent in supply and discharge properties. SOLUTION: An emboss processing resin film is obtained by guiding a thermoplastic resin film to the gap between a carving roll, which has a regular embossed pattern with a wire gauge of 150-220 applied to the surface thereof, and a rubber roll. The emboss patterns of the film surface (front side surface) coming into contact with the carving roll of the emboss processing resin film show the trough parts of the inverted emboss patterns surrounded by regular ridge lines and the emboss patterns of the film surface (rear side surface) coming into contact with the rubber roll show the ridge patterns of the regular emboss pattern and the ridge lines of the surface film have the inner width enabling the tops of the ridge parts of the rear side surface film to fit in the trough parts of the inverted emboss patterns surrounded by the ridge lines of the surface film.
