How long can a virus survive outside of a host?

The other night a guy I know suggested that you need to be careful about puncturing bubble-wrap that came from China, since it might have air contaminated with Coronavirus. I think the guy was kidding or at least partially so, but in any event I myself think even in the highly unlikely event that an infected person was on hand when the bubble-wrap was produced and there was virus in that air, there's no way the virus would survive without a host long enough to infect you in America.

But I got to wondering. How long could a virus survive without a host? Suppose a person who had a virus breathed/sneezed/whatever on some inanimate surface, how long after that point could another person get infected from contact with that surface?
