Zusammenfassung:	The present invention relates to a pouch film laminate and to a secondary battery comprising a pouch-type battery case manufactured using same. The pouch film laminate, according to the present invention, comprises a base layer, a gas barrier layer, and a sealant layer that are sequentially laminated, wherein the melt viscosity of the sealant layer measured at 190°C is 1000 Pa·s to 3500 Pa·s. La présente invention concerne un stratifié de film de poche et une batterie secondaire comprenant un étui de batterie de type poche fabriqué à l'aide de celui-ci. Le stratifié de film de poche, selon la présente invention, comprend une couche de base, une couche barrière aux gaz et une couche d'étanchéité qui sont stratifiées de manière séquentielle, la viscosité à l'état fondu de la couche d'étanchéité mesurée à 190°C étant de 1000 Pa·s à 3500 Pa·s. 본 발명은 파우치 필름 적층체 및 이를 이용하여 제조된 파우치형 전지 케이스를 포함하는 이차 전지에 관한 것으로, 본 발명에 따른 파우치형 필름 적층체는 순차 적층된 기재층, 가스 배리어층 및 실런트층을 포함하고, 190℃에서 측정한 상기 실런트층의 용융 점도가 1000 Pa·s 내지 3500 Pa·s이다.
