I guess it varies. Traveled from below sea level in DV to over 8,000 ft without a bag bursting.

I can't wait to see it. Some RV manufacturer is going to read this thread and start offering an optional pressurized pantry.

> pressurized pantry.

But then we'll have to discuss whether to pressurize it with nitrogen or plain old air.

My first thought was 'how would it be to put a pin hole in a balloon'. Then I realized that the paper or plastic is not stretched like the skin of a balloon. With the gentle gain in altitude the pressure inside would be relieved slowly as the atmospheric pressure inside the bag decreased. I suspect it would work very well.

It happens to almost everything in the coach. We have had mustard, ketchup, sun tan lotion and toothpaste squirt all over when opening so we have to remember to be careful when doing so. I believe we have only had a chip bag pop open once in all our trips but they are always very large and puffy when we get to where we are going. As mentioned, when we go into some high altitude stores we see many a puffed up bags of chips so it does not help to buy when you get to your destination.

Interesting. I've never had this problem. But, then again, we've bought our groceries fairly close to our destinations or roughly at the same altitude. It is something to keep in mind for the future.
