摘要： Proposed are a method and apparatus for manufacturing a laminate film for a cell-type battery pouch. More specifically, the present disclosure relates to a technology of manufacturing a pouch film used to manufacture a pouch-type battery. Specifically, when manufacturing a laminate film for a pouch using a dry lamination process, induction heating rolls that are controllable in heat generation thereof are used to perform a post thermal treatment process after performing a lamination process using thermal rolls. The method and apparatus can reduce an aging period that is required to improve the physical properties of a manufactured pouch or can improve the physical properties of a manufactured pouch without an aging process.
