Beschreibung
Zusammenfassung:	Disclosed are a method for manufacturing a secondary battery pouch film having at least an outer layer, a metal layer, a primer layer, and a sealant layer, or at least an outer layer, a metal layer, a primer layer, a melt-extrusion resin layer, and a sealant layer in this order, the method including: a drying process of applying and heating a primer layer composition on the metal layer so as to dry the primer layer composition and cure at least a part of the primer layer composition. The organic solvent-based emulsion composition contains acid-modified polypropylene and a curing agent and has a curing start temperature of 150° C. or lower, preferably 135° C. to 150° C., and a drying process temperature of 150° C. or lower, preferably 135° C. to 150° C. The method is not subjected to a thermal lamination process when laminating sealant layer.
