Sure, but if someone is looking for recommendations for "faraday bags that work", I wouldn't recommend "any chip bag" if it needs to be qualified with "it depends on a lot factors". I'd just recommend an actual faraday bag whose intended purpose is to block a signal.
Yeah, but the problem with that is that they don't get to eat any potato chips.
Anyways, today's use case for the person's post is to block a garage door beeper, so chip packets or a refrigerator should do fine.
...unless they're also abducting people for extraordinary rendition. Then maybe get the faraday bag.
I agree the OP's use case isn't life-or-death and therefore doesn't need the highest quality faraday bag, but they asked for ones that work, so I felt it pertinent to point out that "any chip bag" was not, in my view, a particularly good recommendation. It's cheap and accessible, but isn't going to work as well (or at all) compared to a bag that was designed to block signals.
In this instance, you get what you pay for. OP is free to try the chip bag method, but they ought not be surprised if it's an insufficient solution.
