The present invention relates to an antibacterial film and a manufacturing method thereof. More specifically, the method comprises the steps of: preparing zinc oxide (ZnO)-titanium dioxide (TiO_2) nanopowder with a core-shell structure; mixing biodegradable polymers and thermoplastic polymers to prepare polymer raw materials; mixing the prepared nanopowder and polymer raw materials to prepare mixed raw materials; and extruding the prepared mixed raw materials to manufacture a film. According to the present invention, the method uses environmentally friendly materials and processes, thereby manufacturing a safe and more functional antibacterial film. 본 발명은 항균 필름 및 이의 제조방법에 관한 것으로, 보다 상세하게는 코어(core)-쉘(shell) 구조의 산화아연(ZnO)-이산화티타늄(TiO2) 나노분말을 제조하는 단계; 생분해성 고분자 및 열가소성 고분자를 혼합하여 고분자 원료를 제조하는 단계; 상기 제조된 나노분말 및 고분자 원료를 혼합하여 혼합원료를 제조하는 단계; 및 상기 제조된 혼합원료를 압출하여 필름을 제조하는 단계;를 포함하는 항균 필름 제조방법을 제공한다. 상기에 따른 항균 필름 제조방법은 친환경적 소재 및 공정을 이용하여 보다 안전하고 기능적으로 우수한 항균 기능성의 필름을 제조할 수 있다.
