Containers for parenteral fluids

A flexible transparent container for improved storage of oxygen sensitive parenterally administrable agents comprising an inner, primary container enclosed in a substantially oxygen impermeable outer envelope with an oxygen absorber, capable of consuming essentially all residual oxygen after the outer envelope is sealed as well as the oxygen penetrating said envelope characterized in that:

• (i) the inner container is made of a polypropylene containing flexible polymeric material compatible with lipophilic agents capable of forming both permanent and peelable seals;
• (ii) the envelope is made of a substantially water impermeable flexible multilayered polymeric material comprising:
• a) a first outer substantially water impermeable polymeric film with oxygen barrier forming capacity, assembled with
• b) a second, inner polymeric film with a supplementary oxygen barrier forming capacity;
• and in which the container essentially maintains its characteristics after being subjected to sterilization by steam or radiation, in which the sealing envelope is made of a flexible multilayered transparent material which, after steam sterilizing at 121.degree. C., provides an oxygen barrier with an oxygen penetration less than 30 cubic centimeters/m.sup.2, atm, day, when measured at a specific temperature of 25.degree. C. and 60% relative humidity, wherein said envelope forming multilayered material consists of a first outer water impermeable film comprising a metal oxide coated polymeric layer connected to a second inner film comprising an oxygen barrier forming polymeric layer, wherein said second inner film comprises at least one layer containing polypropylene, and wherein said envelope forming material consists of a film having the structure PET/metal oxide/glue/PET adhesively bound to a film consisting of the structure polypropylene/tielayer/EVOH/tielayer/polypropylene.
