A medical composite aluminum film pouch with high oxygen gas impermeability as outer bag encloses a non-PVC flexible plastic bag containing an infusion solution. The composite aluminum pouches are made by PT/A1/PE or laminate film consisting of polymers/Al-deposited polymers or polymer/aluminum foil/polymers. The infusion in the non-PVC bag is usually fluid that is easily deteriorated upon contact with oxygen or light-sensitive. Using composite aluminum film pouch as outer package has the well accepted characteristics of high obstructing, high oxygen-resistance, high light-protecting and air-proofing. It helps to solve the quality stability problems of the content which is light-sensitive and easily-oxidized. It is safe and innocuous, able to prolong the storage and shelf life of the medicine.
