Ultrasonics take aim at pouch sealing.Herrmann Ultrasonics ultrasonics, study and application of the energy of sound waves vibrating at frequencies greater than 20,000 cycles per second, i.e., beyond the range of human hearing. has installed an ultrasonic pouch-sealing system for application development at its Schaumberg, Ill., headquarters. The company seeks to expand use of ultrasonics versus heat sealing for beverage and retort re·tort n.

The R&D unit can seal pouches or roll stock up to 10 in. wide with adjustable sealing force. According to according to prep. 1.

Other advantages over heat sealing reportedly include shorter sealing and hot-tack times, lower energy costs, and immediate system readiness (no preheating required).
