To stop moisture inside the doors from affecting the trim panel

And to direct water back inside the door where it can exit at the drain holes - instead of finishing up inside the car. And wrecking the door cards.

And prevent draughts and dust. If yours has fallen apart while you were taking the trim off you can cut a new one out of plastic and stick it on with duct tape.

That's a wet area, you can position plastic over the inside with a bit of perseverence, it may help. Factory speakers have plastic covers on the inside nowadays.
