I occasionally dry some fruits in the oven, but only during the winter. Once the fruit is dry, I toss a handful of dried fruit in a zip-lock back, chase it with a small desiccant, zip it 90% closed, then suck as much air out of it as I can before zipping it the rest of the way. After that, I toss them in a box in the freezer for long-term storage, thereby avoiding having to use nitrates/trites, or whatever other unhealthy preservatives are usually all over dried fruit you buy from the store.
I believe zip-loc bags are mylar. Perhaps not?
