I use grocery store bags for that sort of thing, but to answer the question - that brown wrap can be purchased at a hobby or craft store. It comes in a large roll, like Christmas wrapping paper...

It's called Kraft paper. I don't bother with wrapping a box. I just use a nice box and lots of tape.

I use grocery bags too. Just cut a couple of the edges, wrap the paper around the box inside out, add some packing tape, and you're good to go. =)
