I wouldn't rely on that. Consider earlier discussion in this thread about failure of the sealed-foil packaging (maybe the new packaging will fix that problem).

I'd be even less-inclined to trust Ziploc. In my experience, Ziplocs aren't truly air-tight. Squeeze the air out of one with something in it; seal it; wait. After awhile, it's puffed back up (maybe I'm using cheap 'Ziplocs').
