    Anyone know what those things are made of?

      Another article said they're made of "polythene" which is probably the author's misspelling of polyethylene - a relatively inexpensive and food-safe plastic with good UV stability, especially in black. Same general material that's used to make saran wrap and plastic grocery bags.

        Aren't we supposed to be trying to pull back on making stuff like plastic grocery bags?
