PROBLEM TO BE SOLVED: To provide a laminated film enhanced in slip properties and pinhole resistance, having good processability in a printing or laminating process when used as various packaging materials and suitable for use in packaging reduced in the change of physical properties such as a gas barrier capacity or mechanical strengths with the elapse of time due to moisture absorption under a normal temperature/normal humidity atmosphere. SOLUTION: A thermoplastic resin film is formed by laminating five or more layers in a thickness direction, and layers based on a polyester and layers based on a polyamide are alternately laminated.
