[Terminator] If skin is required for something to survive time travel, would wrapping objects in skin or putting them in your body allow you to take them back in time with you?

Edit: I’m asking more about humans time traveling than about terminators.

Very likely, yes. This is how the Terminators are able to come back at all, and why the TX and other advanced models were able to bring back built-in future weaponry.

Reese describes it as a "field around a living thing," so as long as the flesh was alive, it should be fine. 

A pacemaker implanted in a human should come back, but a simple lump of skin, with nothing to provide it nutrients, would probably not have the "living" quality necessary.

This is one of the things that makes the 800 series so remarkable; the flesh is actually alive, and the Terminator has systems capable of sustaining all of its biological functions.
