I have an excess of pillow cases, and so when packing either to put away for a while or for travel I tend to reduce the kilt to a width to fit into a pillow case and slide it in with the waist at the closed end. I check that the pleats are laid neatly and then stack them flat. You can hold the waist edge through the material and pull lightly at the bottom edge of each fold, to get the pleat straight.

Usually they emerge as neat and uncreased as they went in, even if they have been under a little pressure.
