That's what I thought, but then I read somewhere that BPA has been found leaching from HDPE also, as well as PET. (Perhaps in much smaller quantities; it didn't say.) In brief poking around the Web I find a couple of sites that say that not only are H/LDPE and PP okay, so is PET. The only thing everyone agrees on is that polycarbonate has BPA (or an equally bad replacement). As far as the others go, I'm not really sure what to think at this point.
