  • Tray sealing system incorporating beaded seal plate
    Patent number: 6701993
    Abstract: A tray sealing assembly includes a seal support frame for supporting a flange of a tray during sealing of a sealing film to the flange, a seal plate having a sealing surface provided with a raised bead, and a heater for heating the seal plate. The seal support frame is movable relative to the seal plate between a retracted position and a seal position in engagement with the seal plate. Preferably, the raised bead forms a continuous closed loop on the sealing surface. The raised bead produces a reliable seal between the sealing film and the tray flange, despite the presence of contaminants on the tray flange.
