PURPOSE: A nylon film using two kinds of inorganic particles, and a producing method thereof are provided to secure the excellent slipping property and print-adhesive force of the nylon film. CONSTITUTION: A producing method of a nylon film comprises the following steps: mixing a nylon resin with the relative viscosity of 2.6~3.5, an inorganic particle A with the average diameter of 1~5microns, and an irregular bulky inorganic particle B with the average diameter of 0.05~2microns; compounding the mixture for obtaining master batch; adding the master batch into a nylon resin with the relative viscosity of 3.0~3.6; melt-extruding the mixture to obtain a sheet; and biaxially extending the sheet to obtain the film.
