| 摘要 |
Apparatus for forming void-fill packaging includes a longitudinal guide path along which tubular plastics material, which preferably has no longitudinal seams and no preformed perforations, can pass, drive elements for moving the plastics material along the guide path, transverse heat sealing elements for forming first and second transverse spaced parallel heat seals substantially across the plastics material, the first and second heat seals acting to define a chamber therebetween, and a nozzle which is adapted to, in use, extend inside the plastics material adjacent to one longitudinal edge thereof and which can discharge a fluid into the chamber. The apparatus also includes longitudinal heat sealing elements for forming a third heat seal which seals the chamber, and a cutting element which cuts the said one longitudinal edge so that the movement of the tubular plastics material is not hindered by the nozzle. A method is also provided.
