れらが図１の外包装袋４に相当する。Further, instead of the outer wrapping bag 4, an outer wrapping body 15A in which a film is attached to a polyolefin tray and hermetically sealed, or an outer wrapping body 15A in which a polyolefin tray is wrapped in a transparent resin wrapping bag is also provided. Can be adopted. The tray is formed of an inner layer, an outer layer and an intermediate layer. Polyethylene, polypropylene or the like is used for the inner layer and the outer layer, and the thickness is 300 to 1000 μ. For the intermediate layer, vapor-deposited aluminum, vapor-deposited silica, polyvinylidene chloride, ethylene-vinyl alcohol copolymer, or the like is used as a water vapor and oxygen gas blocking layer, and has a thickness of 10 to 60 μm.
The transparent resin film as the lid is basically made of the same material as the outer packaging bag 4. FIG. 2 shows a packaging form in which a blood bag 11 is placed in a polyolefin tray 14 instead of the outer packaging bag 4 in FIG. In the case of the tray 14, the entrance may be sealed by heat sealing with a transparent synthetic resin cover film 15, or the tray 14 may be sealed in a transparent synthetic resin packaging bag (not shown). In this case, the outer package 15A is constituted by the tray 14 and the cover film 15 or the tray 14 and the transparent synthetic resin packaging bag, and these correspond to the outer packaging bag 4 in FIG.
