The invention discloses a pre-coated cartridge bag aluminum foil and a preparation method thereof, and relates to the technical field of cartridge bag aluminum foils. The pre-coating type medicine bag aluminum foil comprises a medicine bag aluminum foil body, the medicine bag aluminum foil body comprises an aluminum foil layer, an OP layer is arranged on the surface of the top of the aluminum foil layer, and a VC heat sealing layer is arranged on the surface of the top of the OP layer. According to the invention, the OP layer and the VC heat-sealing layer are respectively dried for multiple times, so that the OP layer can be firmly attached to the surface of the aluminum foil layer, and the dried VC heat-sealing layer can be cured under high-temperature baking, so that the adhesion of the medicine package aluminum foil main body during rolling is avoided, the use convenience of the medicine package aluminum foil main body is improved, and as the OP layer is one of YY103, QTOP and WHOP, the service life of the
