Actually, SurvivorGirl, I think I would wrap each one individually in the new Glad Press 'n Seal and then put each one into a plastic freezer zipper-lock bag.
One of the challenges with freezing baked goods, or other foods, is condensation.
By wrapping each one individually, some of the risk of condensation is reduced. Each time you open the zipper-lock bag to remove a muffin, air and moisture enters no matter how careful you are.
I've been using this technique for quite a while with good results.
