A dried food fresh-keeping packaging bag structure includes a packaging bag and a fresh-keeping device in the packaging bag. The fresh-keeping device includes a storage box. One side of the storage box is attached to an inner surface of the packaging bag. The storage box has a storage chamber filled with a preservative. One side of the storage chamber is formed with an outlet provided with a breathable film to block the preservative. An outside of the breathable film is provided with a sealing film to seal the storage chamber. One end of the sealing film extends to an outside of a mouth of the packaging bag to form a pull portion. When in use, the pull portion is pulled to tear the sealing film from the fresh-keeping device, so that the dried food product in the packaging bag is kept dry by the preservative.
