Abstract
(EN)
This laminate is a laminate (10A) comprising a substrate (1) and a gas barrier unit (4), wherein: the gas barrier unit (4) includes two barrier layers, i.e., a first barrier layer (2a) and a second barrier layer (2b), and an organic intermediate layer (3) sandwiched between the barrier layers and having an elastic modulus at 90°C of 1.5 GPa or greater; the ratio (X/Y1) between the thickness (X) of the organic intermediate layer (3) and the thickness (Y1) of the first barrier layer (2a) is from 3 to 18 inclusive; and the ratio (X/Y2) between the thickness (X) of the organic intermediate layer (3) and the thickness (Y2) of the second barrier layer (2b) is from 3 to 18 inclusive. The present invention provides a laminate that has excellent gas barrier properties and in which the gas barrier properties are less prone to deteriorate even in cases where a thermal load is applied.
(FR)
La présente invention a trait à un stratifié (10A) comprenant un substrat (1) et une unité formant barrière contre les gaz (4). Ladite unité formant barrière contre les gaz (4) comporte deux couches barrières, c'est-à-dire une première couche barrière (2a) et une seconde couche barrière (2b), ainsi qu'une couche intermédiaire organique (3) se trouvant entre les couches barrières et ayant un module d'élasticité à 90 °C de 1,5 GPa ou plus. Le rapport (X/Y1) entre l'épaisseur (X) de la couche intermédiaire organique (3) et l'épaisseur (Y1) de la première couche barrière (2a) est de 3 à 18 inclus, et le rapport (X/Y2) entre l'épaisseur (X) de la couche intermédiaire organique (3) et l'épaisseur (Y2) de la seconde couche barrière (2b) est de 3 à 18 inclus. Cette invention permet d'obtenir un stratifié qui a d'excellentes propriétés de barrière contre les gaz et dont les propriétés de barrière contre les gaz risquent moins de faiblir même en cas d'application d'une charge thermique.
