The present invention is a valve bag with a valve assembly that provides closure during and after the filling process, thus preventing unwanted spilling and sifting of the valve bag contents through the valve opening during transporting or moving the bag to a location in which the valve is permanently sealed, and methods for making and filling such a bag. An automatic self-closing valve assembly also is provide that requires no subsequent sealing after the filling process.
