Hey another Mat Sci guy. Good stuff.
I wold think that the HDPE Nalgenes would fit your criteria. Polyethelne is the same stuff that freezer bag, milk jugs are made out of, and so far is considered very safe. If you want to try a lighter/cheaper version, see if you can find a 1qrt/L HDPE milk jug and try that out. The melting point of PE is 115C so you should be fine with boiling water.
