Abstract:
(EN) The present invention addresses the problem of providing a laminated film that possesses excellent properties in terms of appearance, productivity, and water vapor barrier. The laminated film is characterized by having layer A and layer B, wherein: layer A contains a polyvinyl alcohol-based resin as a main component, and 2-45 parts by mass of an inorganic lamellar compound with respect to 100 parts by mass of the polyvinyl alcohol-based resin in the layer; the content of the polyvinyl alcohol-based resin in layer B is less than the content of the polyvinyl alcohol-based resin in layer A; the average polymerization degree of the polyvinyl alcohol-based resin in layer A is 250-1,600; and the orientation degree of layer A is at least 5% as measured by in-plane XRD.
(FR) La présente invention vise à fournir un film stratifié qui possède d'excellentes propriétés en termes d'aspect, de productivité et de barrière à la vapeur d'eau. Le film stratifié est caractérisé en ce qu'il comporte une couche A et une couche B, la couche A contenant une résine à base d'alcool polyvinylique en tant que constituant principal, et 2 à 45 parties en masse d'un composé lamellaire inorganique par rapport à 100 parties en masse de la résine à base d'alcool polyvinylique dans la couche ; la teneur de la résine à base d'alcool polyvinylique dans la couche B étant inférieure à la teneur de la résine à base d'alcool polyvinylique dans la couche A ; le degré de polymérisation moyen de la résine à base d'alcool polyvinylique dans la couche A étant de 250 à 1 600 ; et le degré d'orientation de la couche A étant d'au moins 5 % tel que mesuré par XRD dans le plan.
(JA) 本発明は、外観、生産性、水蒸気バリア性に優れた積層フィルムを提供することを課題とするものであり、A層とB層とを有し、前記A層が、ポリビニルアルコール系樹脂を主成分とし、かつ層中の前記ポリビニルアルコール系樹脂を100質量部としたときに、無機層状化合物を2質量部以上45質量部以下含み、前記B層におけるポリビニルアルコール系樹脂の含有量が、前記A層におけるポリビニルアルコール系樹脂の含有量よりも少なく、前記A層におけるポリビニルアルコール系樹脂の平均重合度が250以上1,600以下であり、In-Plane XRDにより測定した前記A層の配向度が5%以上であることを特徴とする、積層フィルムであることを本旨とする。
