PROBLEM TO BE SOLVED: To provide a laminated film with gas barrier properties which stably maintains high gas barrier properties and has successful transparency and resistance to impact/hot water and the like, and a method for manufacturing this film. SOLUTION: In this laminated film with gas barrier properties, an inorganic oxide-vapor deposited film is formed on one surface of a base film, and further, a coating film with gas barrier properties which contains at least an alkoxide represented by the formula: R<SP>1</SP><SB>n</SB>M(OR<SP>2</SP>)<SB>m</SB>, a polyvinyl alcohol resin and/or an ethylene-vinyl alcohol copolymer and further is formed of a composition with gas barrier properties obtained by polycondensation under a sol-gel process, formed on the inorganic oxide-vapor deposited film. In this case, one or more than one layer of the coating film is laminated to form a composite polymer layer. In the formula, however, R<SP>1</SP>and R<SP>2</SP>are each a 1-8C organic group; M is a metal atom; n is an integer of not less than 0; m is an integer of not less than 1; and n+m is an atomic value of M. In addition, the method for manufacturing the laminated film is provided. COPYRIGHT: (C)2005,JPO&NCIPI |
