Beschreibung
Zusammenfassung:	A flat, flexible, sterilizable container for a liquid to be maintained and extracted under sterile conditions, said container comprising: a body having walls formed by a three-layer laminate including an outermost layer of a propylene polymer, an innermost layer of a copolymer of ethylene with a small amount of butylene, and an intermediate layer of an amide polymer; and a valve carried by said body comprising an elastomeric core whose spaced major faces are covered, one, by a three-layer laminate similar to said body wall forming laminate and, the other, by a two-layer laminate including a first layer of a copolymer of ethylene with little butylene and a second layer of an amide polymer.
