The way I see it is that the heat produced during fermention would be harder to control (reduce) if it's in something that's meant to hold temps.
As for the plastic, if it's food gread is should be fine. and no worries about having it air tight. The fementer does not need to be so. Just covered so things can't fall or climb in.
