Abstract
An ultrasonic sealing apparatus for paper packages achieves more stable ultrasonic sealing by cooling the horn during ultrasonic sealing which would otherwise be unstable due to heat imparted to a horn by continuous sealing. An end portion of a horn of a casing that includes the horn and a converter, or the horn, a booster and the converter is cooled by supplying air to a frame portion exposed toward an anvil side.
