Abstract
An ultrasonic sealing apparatus is provided with an excellent sealability. The apparatus is capable of supplying sufficient output energy delivered by an ultrasonic wave-generating device to a thermoplastic resin of a packing material. A tubular packing material is evenly pressed on an appropriate timing in transverse sealing so that the thermoplastic resin is sufficiently softened/melted for an excellent sealing.
