Tyvek works really well as a dust cover, over a shelf full of objects not in boxes and as a bit of a barrier between a wall and a shelf full of hats or shoes, etc. As for shelf lining, if things are not in boxes you probably want some padding I would recommend Volara or the thin rolled ethafoam. They are squishy and inert.
