Ultrasonic Technology Review

As new nonwoven-based end-use products are developed, new opportunities are opening up for ultrasonic technology.

Ultrasonic bonding uses high frequency sound to generate localized heat through vibration and causes thermoplastic fibers to bond together. Manufacturers are using ultrasonic technology to laminate, emboss and slit synthetic materials for products like diapers, feminine care pads, face masks, filter media and more. Among the benefits of this technology is that it offers a sustainable option for manufacturers by eliminating glue.

“Ultrasonic bonding creates soft products with high quality and throughput with a process that supports
