摘要： The invention relates to a sealing assembly (100) for sealing an inflated flexible tubular packaging material under tension in the machine direction; the sealing assembly having an upper (101) and a lower (102) sealing bar with opposed sealing faces, moveable between an open position and a closed sealing position, a flattening member (104) having a head section with a convex leading surface (106) mounted the sealing lower bar (102) for movement relative to the lower sealing bar (102), said movement being between a first position in which the leading convex surface (106) is proud of the sealing face of the lower sealing bar (102) and a second position in which the distance between the leading surface (106) of the flattening member (104) and the sealing face of said sealing bar is less than that when in the first position. The head section is in the first position when the sealing bars are in the open position and as the sealing bars travel towards the closed position the head section moves towards the second position and during such movement the leading convex surface engages the inflated tube so as to at least partially collapse the tube.
