These weren't inner sleeves though, but thick flexible library sleeves with the entire album INSIDE. No direct contact between plastic and disc, and in fact many of the discs were in the original cardboard sleeves without liners. Would the library sleeves have trapped moisture and chemicals inside and caused the filmy effect?
