Hi, this is something that has recently come to my attention regarding the storage of my DVDs. While I always keep my discs inside of either their original plastic cases, jewel cases, or paper sleeves, I also store the cases inside of cardboard boxes, specifically the corrugated kind available for shipping purposes.
I recently realized, however, that cardboard does indeed emit acid that can discolor and change paper and fabric over time, but I was told that other materials, or at the very least the polycarbonate plastic that discs are made out of, will not be affected.
I wanted to confirm whether or not this was true. I've put almost all of my discs into cardboard boxes, but I will remove them if there is indeed an actual threat to the longevity of the discs themselves. I am not concerned if only the paper sleeves will be negatively affected.
Thanks in advance for any attention given to this issue.
