ABSTRACT:
A flexible bag formed from at least one plastic sheet folded to form a tube and provide overlapping, longitudinally-extending margins, is disclosed. The overlapping margins are joined by a series of longitudinally-spaced bonds, typically heat seals. A membrane permeable to sterilizing vapor and which may comprise a strip of paper having high wet strength is bonded to the tube and overlies the portion of the tube including the overlapping margins. The longitudinally-spaced heat seals preferably secure the overlapping margins to the membrane as well. The various heat seal patterns for joining the overlapping margins and membrane, as well as particular embodiments of the bag for retaining liquid and dry contents, are also disclosed. The sealing arrangement of the invention provides a bag capable of holding, even under autoclaving conditions, bulky, heavy materials which would otherwise rupture the paper strip or the seals joining the strip to the plastic tube.
