<P>PROBLEM TO BE SOLVED: To provide an excellent laminated moisture-proof film in which moisture-proof properties and inter-layer strength do not decrease even after the laminated moisture-proof film is exposed to a high temperature condition. <P>SOLUTION: This laminated moisture-proof film includes: an inorganic thin film layer on a base material; and a plastic film on the inorganic thin film layer via a polyurethane-based adhesive satisfying a condition (1). (1)-0.1≤E21≤+0.5. In the expression, E21 denotes (E2-E1)/E2, E1 represents tensile storage elastic modulus at 150°C, a frequency of 10 Hz, and strain of 0.1%, and E2 represents tensile storage elastic modulus at 150°C, a frequency of 10 Hz and strain of 0.1% after the heat treatment of 150°C for 30 minutes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
