A water-barrier laminated film () including a plastic film (A) that has an inorganic barrier layer (A) on the surface thereof and a water-trapping layer (B), characterized in that: between the plastic film (A) and the water-trapping layer (B), an isocyanate type coating (C) is provided that contains, as a film-forming component, an isocyanate type polymer obtained by reacting an isocyanate as the reaction component; and the water-trapping layer (B) is formed on the isocyanate type coating (C) that is formed as the underlying layer.

Water-barrier laminated film

A water barrier laminate () including a plastic base material () that faces the atmosphere of a high water content, as well as a first inorganic barrier layer (), a water-trapping layer () and a second inorganic barrier layer () formed in this order on the plastic base material () on the side that does not face the atmosphere of the high water content, wherein an auxiliary water-trapping layer () is formed on the second inorganic barrier layer () on the side opposite to the water-trapping layer () to trap the water from the side surface, the auxiliary water-trapping layer () being located on the surface that faces the atmosphere of a low water content or being located in a region at a distance of not more than 20 &#x3bc;m from the surface that faces the atmosphere of the low water content.
