you cunninghammed me: nalgenes are polycarbonate, which is a lot less inert
all the polyethylenes are relatively inert, because polyethylenes are in some sense just heavy paraffins. paraffin is germanized latin for 'relatively inert'

Some Nalgene's are polycarbonate, like those commonly drunk from. But not all, some are HDPE[0,1,2].
Some are Polypropylene co-polymer[3] but those are more for specialist things I guess.
