<P>PROBLEM TO BE SOLVED: To provide a barrier laminated film which has the same oxygen barrier property, steam barrier property, light-shielding property, and glossiness as aluminum vapor deposition PET etc., excellent adhesion between a base material and an aluminum vapor deposition film, and a heat sealing property. <P>SOLUTION: There is provided a barrier laminated film 1 which has an undrawn polyolefin resin film 11, a gas barrier coating film 12 provided thereupon, and an aluminum vapor deposition layer 13 provided thereupon. The gas barrier coating film is formed of a hydrolyzate or hydrolysis condensate of alkoxide obtained by polycondensing, by a sol-gel method, a composition containing one kind or more of alkoxide represented by general formula R<SP POS="POST">1</SP><SB POS="POST">n</SB>M(OR<SP POS="POST">2</SP>)<SB POS="POST">m</SB>(where M represents a metal atom, R<SP POS="POST">1</SP>, R<SP POS="POST">2</SP>represent organic groups having carbon numbers of 1-8, (n) is an integer equal to or larger than 0, (m) is an integer equal to or larger 1, and n+m represents an atomic valence of M), polyvinyl alcohol, and/or ethylene vinyl alcohol. <P>COPYRIGHT: (C)2013,JPO&INPIT |
