The invention provides a fresh-keeping and cleaning dual-function combined device and application thereof, and the device comprises a specific base material capable of adsorbing a fresh-keeping agent, the fresh-keeping agent adsorbed on the base material, and an outer packaging layer used for encapsulating the base material adsorbed with the fresh-keeping agent, wherein the preservative can be released from the base material to the outside of the device through openings formed in the outer packaging layer for food preservation, and is used as a cleaning wet tissue after the outer packaging layer is opened, the loading amount of the preservative on the base material is 0.075-0.5 g/cm2 of the surface area of the base material, and the loading amount of the preservative on the base material is 0.075-0.5 g/cm2 of the surface area of the base material based on the total surface area of the outer packaging layer per cm2 of the total surface area of the outer packaging layer. And the area of the formed open pore is
