PROBLEM TO BE SOLVED: To provide a process for producing a film, which produces T-die film having excellent blocking resistance, slip properties, and resistance to the separating properties of an anti-blocking agent. SOLUTION: The process for producing the film comprises steps of: performing melt extrusion of a resin through a T-die into a film form; powder spraying an antiblocking agent in an area average spray amount of 0.5 to 3 g/m<SP>2</SP>on the surface of cooling roll; and pressing the melt-extruded film form molten resin to the cooling roll surface subjected to the antiblocking agent powder spraying.
