Ultrasonic sealing technology for flexible packaging

Rinco Ultrasonics, a leading manufacturer of ultrasonic welding equipment, has unveiled breakthrough technology for ultrasonic film sealing of flexible packaging for dry and liquid foods, personal care items, and electronics.  

The company’s new FPA series ultrasonic pouch sealing systems elevate ultrasonic welding to a new performance level, enabling users to increase seal strength, improve aesthetics, and broaden the processing window versus competitive ultrasonic sealing and heat sealing processes. 

The FPA-4500 was designed specifically for sealing pouches with up to four and a half square inches of seal area while the FPA-4500S was created for use in duplex and triplex applications where a narrow profile is required.  

Rinco’s entire FPA series of ultrasonic sealing systems have been designed to replace existing heat sealing equipment on liquid filled pouch form-fill-seal (FFS) machinery or pre-made pouch systems.             

The novel systems incorporate Rinco’s patented PPS0145 seal technology, which significantly expands what is possible in ultrasonic film sealing. Each FPA system features a highly rigid actuator capable of rapidly generating the clamp forces required to seal pouches with minimal cycle time.            

“Our technology propels ultrasonic welding to an entirely new level, broadening the design and manufacturing options for OEMs and co-packers, simplifying the process, and making it less costly to operate,” explained Gordon Hull, managing director of Rinco Ultrasonics.  

“The limitations of ultrasonics have been solved, making the joining system a highly useful and viable option for a range of flexible packaging applications.”
