Cigars... Wrapped or Unwrapped in humidor?

[G_T]

I've been given a load of cigars from my grandad and I'm wondering what the concensus is on storing them. They're a bit of a mixed bunch ranging from King Edwards, Phillies through to cohibas, habanas and some brands that I've never heard of but look fairly decent (green tobacco and glass tubing on some of them which should be interesting!).

Not being particularly clued in on this issue I'm just curious if I should be removing the plastic wrappers on some of them to store?

I've got a fairly decent humidor set at ~75% humidity which is my personal preference.
