I'm relatively new to prepping, and have lurked here for a while. I've started accumulating foodstuffs, and right now I'm packaging beans for LT storage. I've bought them from Aldi; they come in 2-pound bags. I'd really like to store them in those bags, inside Mylar w/ oxygen absorbers. Keeping the original packaging has advantages (for barter, keeping info on the beans right with the beans, etc.). I tried an experiment: I poked about 60 holes in those bags with an awl, large enough to expect air to circulate, small enough for the beans to stay in the bag. I then put two of those bags, along w/ an oxygen absorber, into a gallon mylar bag, squeezed out the air as best I could, then sealed them. The Oxy absorber worked; the mylar bag pulled in tight, so enough air is circulating for the oxy absorber to pull out the oxygen--though it took a couple days for this to happen. Question: Is there any long-term problem (i.e., 20 years plus) w/ storing the beans in the original packaging? I've looked online to try to learn about the plastic packaging and have so far struck out. I can't tell what type of plastic it is (no recycling symbol on the bag). And, yes, they won't store space-efficiently as well as loose beans in a 5- or 6-gallon bucket, but I'm willing to accept that penalty in exchange for smaller mylar packages.
