I read the article, and to the other poster’s credit, I recall those cheese packs being enclosed in paper, which then may or may not be exposed to higher levels of humidity after opening the tub.
Sure, they’re lined with something protective, but I would think the paper packets would begin to deteriorate faster after the tub has been opened than beforehand.
Just my worthless opinion....
Might as well just purchase bulk boxes, transfer noodles and cheese packet to a ziplock bag, and fill a 5 gal food grade bucket with them. Save one cooking directions for the lid. That keeps it all in easy to use portions.
