ABSTRACT:
A dunnage bag having multiple outer plies of paper and an inner ply of plastic has a baffle means opposite the inflation valve to prevent dry burn constituting either a piece of corrugated paper or a similarly flat member of sufficient included area to baffle substantially all of the air projected through the valve and having an expanded thickness sufficient to separate the confronting surfaces of the plastic ply a discrete distance so that the air stream directed through the valve will be diffused transversely and thereby dissipate any vibratory forces tending to produce a dry burn on the plastic ply.
