PROBLEM TO BE SOLVED: To provide a plastic film subject to a slitting step which does not cause blocking after winding with a winder and therefor without trouble even in the case of the plastic film having both surfaces having been subjected to a corona treatment. SOLUTION: The plastic film is formed into 2,000-5,000 mm width and has both surfaces having been subjected to the corona treatment. Furthermore, non-treated parts of the corona treatment are formed at both ends in the width direction in at least one surface, respectively. The method for producing the plastic film having both the surfaces having been subjected to the corona treatment comprises forming the non-treated parts of the corona treatment at both ends in the width direction in at least the one surface of the plastic film having 2,000-5,000 mm width, respectively.
