Abstract
(EN)
The purpose of the present invention is to provide a moisture-barrier laminate which is provided with a moisture-trapping layer, can maximize the moisture-trapping performance of the moisture-trapping layer, and can exhibit excellent moisture-barrier performance. The moisture-barrier laminate according to the present invention is characterized by including a gas-barrier film base material A comprising a gas-barrier layer a1 and a moisture-trapping layer B formed on the film base material A that serves as an under layer, wherein a protective resin layer C is laminated on a surface of the moisture-trapping layer B which is opposite to the film base material A, and the protective resin layer C has a water vapor permeation degree ranging from 4.0 × 10 to 5.0 × 104 g/m2·day as measured at 40°C and 90% RH.

La présente invention a pour objet de réaliser un stratifié formant barrière à l'humidité qui est pourvu d'une couche de piégeage d'humidité, peut maximiser les performances de piégeage d'humidité de la couche de piégeage d'humidité et peut présenter d'excellentes performances de barrière à l'humidité. Le stratifié formant barrière à l'humidité selon la présente invention est caractérisé en ce qu'il comprend un matériau de base de film A barrière contre les gaz comprenant une couche barrière contre les gaz a1 et une couche de piégeage d'humidité B formée sur le matériau de base de film A qui sert de sous-couche. Une couche de résine de protection C est stratifiée sur une surface de la couche de piégeage d'humidité B qui est à l'opposé du matériau de base de film A, et la couche de résine de protection C présente un degré de perméation de vapeur d'eau de 4,0 × 10 à 5,0 × 104 g/m2·jour tel que mesuré à 40 °C et 90 % d'humidité relative.
