PROBLEM TO BE SOLVED: To provide a propylenic resin film that is composed of a propylenic resin inexpensively and efficiently manufactured by a gas phase method, is excellent in blocking property and surface smoothness, prevents a film roll from wrinkling when wound into a roll shape, and also, is excellent in processability during bag-making processing or printing processing. SOLUTION: A propylenic resin laminated film is composed so that a seal layer mainly composed of an olefinic resin is laminated on both front and rear faces of a base layer mainly composed of a propylenic resin. The propylenic resin constituting the base layer and the seal layer is formed by a gas phase method. A dynamic friction coefficient measured under an atmosphere of 40°C, an air-deflation index, and a haze value are adjusted so as to respectively satisfy prescribed conditions.
