Abstract
A valve bag whose walls are formed of a flexible thermoplastic sheet material comprising: a) a lateral seam that joins by overlapping the flaps on the edge of the sheet. b) a valve opening between the overlapping flaps in the side seam of the bag c) a valve sheath having front and rear surfaces attached to projections of the valve opening inside the bag whose valve sheath is an essentially rectangular sheet of flexible thermoplastic sheet material folded once on itself each of whose two external surfaces are joined to the valve opening by an extruded cardon of a flexible thermoplastic material that is compatible with the thermoplastic material from which the sheet with which the bag is formed is made, one of whose cords also connects the flaps on the bag side seam d) an end closure that joins together the top edges of the valve sheath and the coextensive edges of the bag walls.
