Does a paper bag prevent food spoilage?

Answer 1

I don't have real knowledge on the matter but since I use paper bags to accelerate ripening on fruits my guess is that the answer would be no. I seems to me that the same principle that speeds ripening would also cause, not prevent spoilage. I am sure there is someone out there who has all the science on the matter but that is my common sense thought.

Answer 2

If you take out all of the air from the bag, there is no oxygen to oxide the sandwich or other product.
