PURPOSE: Provided is a process for preparing polyamide mat film having improved mat property and writing-erasing capability with a pencil and a drawing ink adequate, which can be used as packaging materials including industrial packaging, food packaging and book covering. CONSTITUTION: The process for preparing polyamide mat film by using the resin polymerized with aliphatic diamines, dicarbonic acids and caprolactam, comprises the steps of blending 80 to 10 parts by weight of polyamide chips containing 1 to 5 wt% of SiO2 having average particle diameter of 1 to 10 micrometers and 20 to 90 parts by weights of polyamide chips containing no inorganic particles, and extruding them. The polyamide film obtained by the process has improved haze, light transmission and writing-erasing capability.
