A sealing jaw apparatus for a plastic film wrapping machine has essentially spaced heated sealing jaws with a reciprocal knife located therebetween. The jaws operate against a heated elastomeric bed that has a longitudinal slot to receive the knife during the cutting operation. The arrangement provides a sealing of thermoplastic film and a severing thereof at a considerably lower temperature than the melting point of the film.
