PROBLEM TO BE SOLVED: To provide a laminated film which shows superb water vapor/oxygen gas barrier properties and high pinhole resistance, best suitability for working in a process to print/laminate the film when used as various kinds of packaging materials and packaging use almost without change with time in the physical properties such as gas barrier performance and mechanical strength due to moisture absorption under a normal temperature/humidity atmosphere. SOLUTION: This laminated film contains a compatibilizing agent added to a polyester resin layer and/or a polyamide resin layer and has five or more alternately laminated polyester resin layers and polyamide resin layers.
