Process and installation for the manufacture of bags with handles, characterized in that the process comprises obtaining by extrusion a plastic film tube, which leaves continuously from the corresponding machine, by a narrow circular channel, whose tube, once cooled, it rolls up into a coil; and then passes between rollers, in which it is crushed, while laterally, diametrically opposed guides, force it to form folds towards the interior, which correspond to the bottom and mouth of the bags, which are then obtained from the tube.
