Drug solution container package and method for manufacturing the same

A method for manufacturing a plastic drug solution container package, wherein plastic forming the plastic drug solution container is a multilayer film having a sealing layer at an inner surface side of the plastic drug solution container, a protective layer on an outer surface side of the plastic drug solution container, and an intermediate layer between the sealing layer and the protective layer,

• wherein the multilayer film includes a low water absorption layer, formed of a low water absorption plastic having a water absorption rate of not more than 0.01%, between the sealing layer and the intermediate layer, and
• wherein after making a drug solution contained and sealed in the plastic drug solution container formed of the plastic, which has an oxygen gas transmission rate of not less than 200 cm3/m2·24 h·atm at a temperature of 25° C. and a humidity of 60% RH within twelve hours after being subjected to steam sterilization or hot water sterilization and oxygen gas transmission rate of not more than 100 cm3/m2·24 h·atm at a temperature of 25° C. and a humidity of 60% RH when the oxygen gas transmission rate is in a steady state, the plastic drug solution container is steam sterilized or hot water sterilized, and then the sterilized plastic drug solution container and an oxygen scavenger are contained and sealed in an outer pouch having an oxygen barrier property to form a plastic drug solution container package,
• wherein the intermediate layer is formed from a polyol-based plastic.
