ABSTRACT:
A filling and packaging machine capable of supplementing the shortage of heat quality without lowering package speed when a film is heat-sealed while being pressurized by a vertical sealing mechanism, comprising a film folding mechanism having an inner surface guide member for guiding the film laterally, formed on the inner surface side of the film folded up into two parts, a pair of right and left pre-heating block members having tilted support surfaces or are support surfaces formed along the width-direction of the film on the outer surface side of the film through a specified interval from the inner surface guide member so that the interval on the upstream side of the film in feeding direction is larger than the interval on the downstream side, and heaters installed in the pre-heating block members.
