In regards to Mylar bags, I just simply reverse used potato chip bags (the ones with a silver sheen inside) I receive from friends and neighbors and use those. It's my understanding that it's a form of Mylar (PET- Polyethylene terephthalate). If it's good enough to keep chips fresh and crisp I figure it's good enough for a secondary line of food storage protection too.
