PROBLEM TO BE SOLVED: To provide PTP(press through pack) package films excellent in gas barrier properties, easy openability, flexibility and the like, and PTP package sealing members excellent in easy openability and capable of having a constitution easy in thermal disposal after use. SOLUTION: This PTP package film is composed of a film comprising a liquid crystalline polymer which shows optical anisotrophy on melting and having a ratio of the maximum value of the transmitted microwave intensity, measured by irradiation with a microwave perpendicular to the film surface by the microwave method, to the minimum value of greater than 1.2. A laminated film comprises a layer composed of a film comprising a liquid crystalline polymer which shows optical anisotrophy on melting and having a ratio of the maximum value of the transmitted microwave intensity, measured by irradiation with a microwave perpendicular to the film surface by the microwave method, to the minimum value of greater than 1.2 and a layer composed of a thermoplastic resin (provided that the liquid crystalline polymer is excluded). PTP package sealing members are composed of these PTP package films.
