I know one company that makes Reynolds Wrap - Norandal. They have two plants side-by-side here in TN. They make many other brands of aluminum foil with the SAME equipment. Just different standards SUPPOSEDLY for different brands. So I guess not all Reynolds Wrap can be the same. I have a friend and also a 1st cousin who works there. I've heard descriptions of the way it is made and it sounds like mistakes can easily be made on getting the thickness right. The thickest and best foil was some heavy duty aluminum foil my friend brought me that was just labeled "Norandal." I wish I still had a bunch of it. He was lucky to get one case out of a limited run, apparently.
