1. A method for packaging and storing medical fluids comprising: providing a container comprising a multiple layer non-PVC polyolefin bag having at least one port therein, the bag including a first sheet of a multiple layer material and a second sheet of the multiple layer material, the multiple layer material including an outer layer, a barrier layer, an inner layer, an outer tying layer located between the outer layer and the barrier layer, and a inner tying layer located between the inner layer and the barrier layer, the inner layer of the second sheet being heat sealed to the inner layer of the first sheet to define a fillable interior space within the bag that is accessible through the at least one port;attaching a non-PVC fill tube to the at least one port;filling the container with a predetermined volume of a medical fluid through the fill tube;sealing the fill tube closed with a non-PVC port closure system;after filling and sealing the container, terminally sterilizing the filled, sealed container by steam heat autoclaving at about 125° C. the filled, sealed container without enclosing the container in an overwrap; andplacing the filled, sealed, and autoclaved container in a shipping carton without individually enclosing the container in an overwrap. 2. The method of claim 1, further comprising allowing the filled, sealed, and autoclaved container to be exposed to ambient air for a period of up to 36 months. 3. The method of claim 2, wherein the filled, sealed and autoclaved container is allowed to be exposed to ambient air for a period of up to 24 months. 4. The method of claim 1, further comprising assembling, sealing, and sterilizing the non-PVC port closure system as a unitary sealed subassembly prior to the steps of sealing the fill tube closed with the non-PVC port closure system and autoclaving; wherein, after autoclaving, a twice-sterilized, sealed non-PVC port closure system is provided that can be torn open at one end and then punctured at another end with one of a needle, spike and cannula to access the medical fluid in the container via the fill tube. 5. The method of claim 4, wherein the step of assembling the non-PVC port closure system comprises: providing a port housing for attaching to and sealing the fill tube, the port housing including a diaphragm at one end and an opening at an opposite end;forming a cap assembly including an annular crown and a pull cap frangibly sealed to the annular crown; andsealing the cap assembly to the port housing such that the pull cap is exposed and the cap assembly is in covering relation to the opening and the diaphragm. 6. The method of claim 5, wherein the step of assembling the non-PVC port closure system further comprises frictionally fitting a reseal member within the port housing and mechanically retaining the reseal member with a portion of the cap assembly. 7. The method of claim 4, wherein the non-PVC port system subassembly is sterilized using radiation prior to being sealed to the fill tube.
