The present invention relates to a pouch film laminate body including a base layer, a gas barrier layer, and a sealant layer, which are sequentially laminated, wherein an amount of a slip agent present on the surface of the sealant layer is 5 mg/m<2> to 25 mg/m<2>, wherein the amount of the slip agent is obtained by cutting the pouch film laminate body to 100 mm in an MD x 100 mm in a TD, adding 5 ml of chloroform dropwise on the surface of the sealant layer of the pouch film laminate body, followed by leaving the pouch film laminate body to stand for 1 minute, thereby preparing a slip agent extraction solution, and then measuring an amount of the slip agent contained in the slip agent extraction solution by gas chromatography.
