The invention discloses a sterilization medical instrument package with a supporting stripping edge. A material which plays a supporting role and is harder than the rest of parts is additionally arranged on the extension part of the outer side of the package stripping side sealing edge, or a material harder than the rest of parts is adopted on the extension part of the outer side of the package stripping side sealing edge so as to play a supporting role. A groove is formed in the junction of the outer edge of the stripping side sealing edge and the extension part in a carved manner. The material playing the supporting role comprises rigid plastic or metal or paper. It is avoided that the soft face of the package is rolled inwards and the content is contaminated in the package stripping process; and when only one or two stripping sides exist, the recognition degree of the stripping side can be increased, and a medical worker can find the stripping side more conveniently.
