Abstract:
A sealing apparatus (10) for forming void-fill packaging which comprises a longitudinal guide path along which an edge of a part-sealed plastics film material (16) can pass, a drive means (34) for moving the film material along the guide path, and an air blowing or injecting means (30) for inflating the film material. There is also provided a heater assembly (32) comprising a heating element and a rigid thermally conductive member which is thermally coupled to the heating element, the thermally conductive member having a film-contacting surface for applying thermal energy to seal the film material on the longitudinal guide path.
