Bowing and bulging of the sidewalls from a planar configuration is retarded and restrained by loops of cord operably connected with the sidewalls. Preferably the loops of cord having portions inside the bag extending obliquely between adjacent sidewalls when the bag is filled. Method and apparatus for making the bag with the double knotted loops of cord are also disclosed.
