The invention relates to a recyclable flexible packaging bag for packaging ultraviolet curing reaction dry lithographic plate ink. The flexible packaging bag comprises an ultraviolet blocking film and a specific structure. According to the ultraviolet blocking film, through heat sealing bag making, a flexible packaging container capable of being repeatedly opened and closed of the specific structure is designed, the flexible packaging container is used for packaging high-viscosity UV ink, and the packaging lightweight function and the high-strength function of safe transport are achieved. The ultraviolet blocking film comprises a multi-layer coextrusion film or ultraviolet blocking composite film of an ultraviolet blocking material. The specific structure comprises a rotatable cover suction nozzle. The rotatable cover suction nozzle is welded to the edge of the flexible packaging bag and used for achieving the specific high-viscosity filling packaging process of the high-viscosity ink in a matched manner and is suitable for connection of the flexible packaging bag and specific extrusion ink supply equipment, the safety function with the controllable use state of an ink product is achieved in a matched manner, the environment friendliness function of a recyclable flexible package after ink use is achieved in a matched manner, and the ecological design principles are met.
