PROBLEM TO BE SOLVED: To provide a multiple packing material for medical care which can perform aseptic opening comparatively easily, and can maintain preferable sterilization while preventing damage depending on contact to a medical product.;SOLUTION: A first bag material 21 which stores a second bag material 31 is formed like a flat bag by a first film 22 made of heat seal resin having gas impermeability and germ impermeability and a sheet for a first filter 23 having the gas impermeability and the germ impermeability. The second bag material 31 which stores a medical product 41 is formed like the flat bag by the second film 32 made of heat seal resin having the gas impermeability and the germ impermeability and a sheet for a second filter 33 having the gas impermeability and the germ impermeability. A projection area of the second bag material 31 is smaller than a projection area of the first bag material 21. The second film 32 is thicker than the first film 22. An area of the sheet for the second filter 33 occupied in the projection area of the second bag material 31 is smaller than an area of the sheet for the first filter 23 occupied in the projection area of the first bag material 21.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
