While reading your post I had to wonder about the military surplus ammo I have and used that came to me in the vacuum sealed spam cans. The dates on some of these cans is more than 20 years old and I haven't had any problem with the ammo. I'm not saying your info is incorrect as I'm not an expert on what happens to items sealed under vacuum for extended periods of time. MC

My information is correct, what is confusing if the term vacuum. The old military ammo is not really “Vacuum Packed” . The sealing process used requires heat when the container is sealed and this naturally causes a small vacuum inside. If most of these containers had a real Vacuum inside of them they would collapse in and crush the container.
The point is although the old military ammo is what we call “vacuum packed” it is a slight vacuum caused by the sealing process. When we start talking about actual devices that pump the air out ??? ,,, Who knows what the vacuum level is ? It’s real easy to pump to ½ atmosphere or better and that would be in the danger zone for me.
