LAMINATED MOISTURE PROOF FILM

摘要

A moisture proof laminated film is provided that is excellent in transparency, has considerably high moisture proofness, and is suppressed in generation of bubbles between moisture proof films, even when plural moisture proof films are used. A moisture proof laminated film (1) containing a moisture proof film A (2) having a water vapor transmission rate (WTR (A)) at 40°C and 90%RH of 1.0 (g/m 2 ·day) or less and a moisture proof film B (3) containing a substrate (4) having on one surface thereof an inorganic layer (5) and having a water vapor transmission rate (WTR (B)) at 40°C and 90%RH of 10% or less of the water vapor transmission rate (WTR (A)), which are laminated through an adhesive layer (7).
