ABSTRACT:
An ultrasonic sealing apparatus prevents a sealing failure by preventing a tunnel (through passage) to form in the step portions in the vicinity of both end portions of longitudinally sealed portions, when the tubular laminated packaging material is transversely ultrasonically sealed. An ultrasonic sealing apparatus, in which a laminated packaging material containing a thermoplastic resin layer and a paper layer is formed into a tubular form and the tubular laminated packaging material is transversely ultrasonic sealed, includes a horn having an elongated and flat sealing face and an opposing jaw having an elongated pressing face which presses the laminated packaging material in cooperation with the sealing face of the horn, wherein the center portion in longitudinal direction of the pressing face of the opposing jaw is narrower than both end portions of the pressing face. Further, at a center portion in longitudinal direction of a pressing face of the opposing jaw, a recess having an arc shape, etc. in section is formed along a direction perpendicular to the longitudinal direction of the pressing face.
