Abstract
An ultrasonic sealing apparatus comprises at least one horn having an elongated sealing face for sealing a packing material. Plural converters are erected on a side of the horn opposite to the sealing face for resonating the horn with a vibrating frequency. The ultrasonic sealing apparatus has a length that is one wavelength of the vibrating frequency and is fixed in position to a sealing jaw at a nodal plane of the vibrating frequency.
