My wife cut up a lot of cloth sheets... linens, I think... and bathed them in a boiling mix of beeswax and a couple other waxes and oils. (I believe leather was treated similarly to build ancient armor.) Messy process, but once they dried, they actually functioned pretty well as a reusable wrap and cover. Stiff enough to hold their shape, self-adherent, it can be used like cling wrap or aluminum foil, and could be cleaned and reused dozens of times. Not sure if it is a net positive or negative for the environment, but it's at least practical.
