Abstract:
To obtain a packaging bag capable of storing two medical agents, that can be used via mixture without requiring a blending tray or the like.SOLUTION: A two-compartment packaging bag (1) is formed from a laminated film layer (2) having, on its inner side, a layered structure in which at least a barrier layer (21) composed of a metal layer, an adhesion layer, and a thermoplastic resin layer (23) are laminated in order from the outer side, wherein the inner sides of the laminated film are made to face each other and their peripheral edges are sealed, forming a storage part. In the packaging bag, the adhesion layer is formed from a maleic anhydride-modified polyethylene single layer, or from a coextrusion layer of maleic anhydride-modified polyethylene on the barrier layer side and of low density polyethylene on the thermoplastic resin layer side. A central seal part (4), which splits the storage part, separates it into two compartments, and the central seal part has lower seal strength than the peripheral seal part.SELECTED DRAWING: Figure 1
