Ultrasonics take aim at pouch sealing.

Herrmann Ultrasonics 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 pouches. The R&D unit can seal pouches or roll stock up to 10 in. wide with adjustable sealing force.

According to Herrmann, the ultrasonic process seals through contaminated surfaces, provides hermetic seals that result in fewer leaks, and reduces packaging material costs because less head space is required. Other advantages over heat sealing reportedly include shorter sealing and hot-tack times, lower energy costs, and immediate system readiness (no preheating required).
