You will not be able to eliminate the fold lines from packaging.  The curtains do not hang evenly and since these are sheers the top of the hem (where it is sewn) must be even and it varies from 1/4" to 3/4".  Maybe if the panels were floor length, that deficiency wouldn't matter as much.  The length of each panel is about 1" shorter at each end of the panel.  Buy this off of a tube at a fabric store and make your own.
