Abstract
Improvements introduced in the manufacture of bags with plastic valve constituted by a tubular element whose upper part has an inlet valve for filling materials, formed by a leg that forms initially protruding above the upper edge of the tubular element in the extension of this, characterized in that the valve is obtained by fixing to each other the longitudinal edges of the leg and the transverse edges of the tubular element, collecting the tubular sleeve thus obtained inside the tubular element and fixing it to one of the internal walls of the element tubular.
