Package for storage of medical container

A package containing (i) a plastic medical container and (ii) a deoxidizer, said medical container containing a medicinal fluid which will degrade when contacted with oxygen gas and said container being made of a material which is pervious to gases and steam, said package comprising:

• a tray part having an opening and comprising a laminated structure including an outer polypropylene layer, an intermediate layer capable of barriering passage of gases and steam and and inner polyolefin layer, and a flange portion around said opening;
• a lid member having a laminated structure including an inner polyamide layer, an intermediate layer capable of barriering passage of gases and steam and an outer layer of a resin having a thermal resistance sufficient to withstand the condition of heat sealing;
• said intermediate layers being substantially impervious to steam so that the steam which permeates from the medical container is retained within the package whereby the atmosphere in the package may be saturated with said steam;
• and
• a hotmelt adhesive layer formed of a blend of polyethylene and polypropylene, said hotmelt adhesive layer being inserted between said flange portion of said tray part and said lid member, said flange portion and said lid member being peel openably heat sealed to each other in a said hotmelt adhesive layer.
