Improvements introduced in the manufacture of bags with valve constituted by a tubular element whose upper part comprises an inlet valve of the filling materials, formed by a leg that makes a protrusion at the origin above the upper edge of the tubular sheath in the prolongation of the latter, characterized in that the valve is obtained by making a cut properly on the front side of the sheath and folding the leg on the outer side of the sheath cut, then soldering or glueing this leg to the sheath except on the lateral edge of the bag and eventually in the area of the fold.
