The present invention relates to a pouch film laminate including a base material layer, a gas barrier layer, and a sealant layer which are sequentially laminated, wherein the base material layer includes a surface protection layer, and the pouch film laminate has a Max Forming Index A (MFI) expressed by Equation 1 of 15 or more. Max Forming Index A MFI A = PT / AT × TS [0002] In Equation 1, PT is a value of a thickness (µm) of the surface protection layer, AT is a value of a thickness (µm) of the pouch film laminate, and TS is a value of tensile strength (N/15 mm) of the pouch film laminate.
