The present invention relates to an apparatus for producing an encapsulation film, and a production method thereof. According to one aspect of the present invention, provided is a method for producing an encapsulation film, intended to produce the encapsulation film composed of a metal layer and an adhesive film. To this end, the method for producing the encapsulation film includes a lamination step for laminating the metal layer and the adhesive film together, and the lamination step is conducted by undergoing a roll-to-roll process. A pair of a first roll and a second roll which laminates the metal layer and the adhesive film together is made of different materials. 본 발명은 봉지필름의 제조장치 및 제조방법에 관한 것으로, 본 발명의 일 측면에 따르면, 금속층과 접착필름을 포함하는 봉지필름의 제조방법으로서, 금속층과 접착필름을 라미네이션 접합하는 합지 단계를 포함하며, 합지 단계는 롤-투-롤(roll-to-roll) 공정을 통해 수행되고, 금속층과 접착필름을 합지하는 한 쌍의 제1 및 제2 롤은 서로 다른 재질로 형성된 봉지필름의 제조방법이 제공된다.
