Abstract (en)
An inflation apparatus (100) automatically inflates and seals a plurality of pockets (24) preformed in a film web (10) to form packaging cushions. As the film web is advanced, a stream of inflation gas is directed from an inflation port (282) into each of the pockets. The stream of inflation gas is directed in a flow direction having a component in the direction of travel. A sealing mechanism is positioned as close as possible to the inflation port (282) so that the opening of each pocket is almost entirely closed and sealed while the stream of inflation gas is directed into the pocket. As a result, it is possible to achieve more fully inflated packaging cushions on a consistent basis.
