| 摘要 |
The present invention relates to a moisture-proof laminated film having, on the substrate thereof, an inorganic thin film layer and having, on the inorganic thin film layer, a plastic film via a polyurethane adhesive satisfying the following requirement (1), or the following requirements (1) and (2). The moisture-proof laminated film keeps excellent moisture-proofness and interlayer strength even after exposed to high temperature condition. (1) -0.1 ‰¤ E21 ‰¤ +0.5. (2) -0.3 ‰¤ E21 ‰¤ +0.3. (In the above formulae, E21 indicates (E2 - E1)/E2, and E23 indicates (E2 - E3)/E2. E1, E2 and E3 each mean the tensile storage elastic modulus of the adhesive under specific conditions.) |
