Claims

[Scope of Claim for Utility Model Registration] (1) A bag making and packaging machine using a resin band-shaped packaging film, which has a film folding means for folding the packaging film in half and feeding it out, and at regular pitch intervals in the film feeding direction. a bag side forming means for forming a packaging bag by heat-sealing the film perpendicular to the feeding direction, and cutting the film in the middle of the heat-sealed portion to separate the formed packaging bag; an expanding means for expanding the opening on the top side of the packaging bag, a filling means for filling the packaged item from the side through the expanded opening, and a filling unit for filling the opening with heat after filling the packaged item. A bag making and packaging machine characterized in that sealing means for sealing are disposed in this order along a feeding line of the packaging film fed out from the film folding means. (2) A bag making and packaging machine that uses a resin band-shaped packaging film in which concave grooves and protrusions constituting the zipper of a packaging bag are integrally formed along both sides of one surface, and the packaging film is The film has a film folding means for folding the film in half so that the concave groove and the convex line are in contact with each other, and a zipper engaging means for engaging the concave groove and the convex line that are in contact with each other on the film; bag top forming means for heat-sealing overlapping edges of the film along the zipper outside the zipper engaged by the means; cutter means for cutting open the bifold portion of the film; and a film feeding direction. Forming the bag side by applying heat sealing perpendicular to the feeding direction to the film at regular pitch intervals to form a packaging bag, and cutting the film in the middle of the heat sealed portion to separate the formed packaging bag. means, an expanding means for expanding an opening cut by the cutter means of the separated packaging bag, a filling means for laterally filling an object to be packaged through the expanded opening, A bag-making and packaging machine characterized in that a sealing means for heat-sealing the opening after filling with an object is disposed in this order along a feeding line of the packaging film fed out from the film folding means.
