The present invention has excellent water vapor barrier properties, oxygen gas barrier properties, and pinhole resistance, as well as good processing suitability in the process of printing and laminating when used as various packaging materials, and under normal temperature and normal humidity atmosphere. Provided is a film suitable for packaging use, which has little change with time in physical properties such as gas barrier performance and mechanical strength due to moisture absorption in a container. A laminated film is obtained by alternately laminating five or more polyester resin layers and polyamide resin layers having a melting point difference of 20 ° C. or less. [Selection diagram] None |
