WELDING: Pouch sealer relies on ultrasonics

An ultrasonic welding pouch sealer for standup pouches can seal pouch stock from individual pouches to pouch rolls with up to 10 inches (25.4 cm) opening width. The unit is equipped with adjustable forces for developing sealing parameters. It enables a wide range of trial possibilities for basic material feasibility studies to in-depth application development and simulation of ultrasonic sealing processes for future production lines. Ultrasonic sealing allows a closed, hermetic seal through contaminated surfaces. Herrmann Ultrasonics Inc., Schaumburg, IL, USA; +1 847-985-7344; www.herrmannultrasonics.com
