Abstract
A vertical bag-making/filling/packaging machine () comprises: a film supplying portion () which lets out a film (F) from a roll (Fr); a bag-making guide () which folds the film (F) into a tubular shape and changes a conveying direction downward; a vertical sealing portion () which thermally seals side edges of the film (F) to each other in an up-down direction so as to make the film into a tubular shape; a film conveying portion () which conveys the film (F) downward; a filling portion () which loads a content (X) into an interior of the film (F); a lateral sealing portion () which thermally seals the film (F) in a left-right direction so as to make a bag body; a square-bottom sealing portion () which expands a bottom of the bag body to a rectangular shape from an inside and then thermally seals the bottom to form a rectangular bottom surface; and a cutter () which cuts off the bag body from the film (F).
