The utility model discloses an atmosphere-controlled packaging film suitable for tobacco lamina packaging and storage in a carton. The atmosphere-controlled packaging film comprises a base layer, a PVDC layer covering the upper surface of the base plate, an oxygen consumption layer covering the upper surface of the PVDC layer, and a protective layer adhered to the upper surface of the oxygen consumption layer, wherein the protective layer comprises a protective film and an air dissolution layer; the protective film is adhered to the upper surface of the air dissolution layer; the air dissolution layer covers the surface of the oxygen consumption layer. The PVDC layer of the packaging film can effectively prevent packaged tobacco leaves from external interference during a storage process of the tobacco leaves; after tobacco lamina packaging is completed, oxygen in a tobacco lamina packaging carton can be quickly consumed through the oxygen consumption layer, so that the oxygen concentration is lower than 2%, and the effects of killing pests, preventing pests and preventing mildew can be achieved.
