Long Term Damage From Tape

I was wondering what kind of damage tape does to notes especially once already preserved/graded. You will see many notes with tape repairs have large brown patches wherever the tape was but what about when notes were freshly taped and then submitted and graded in a third party holder? Will the tape continue to eat away at the paper? Will it eventually eat away a hole? Obviously if that is the case the assigned grade would become obsolete. Whenever purchasing notes that are graded it is important to buy the note, not holder but I am curious if the tape will continue to damage the note.
