Pouch Sealing System Uses Ultrasonic Technology
Rinco Ultrasonics has launched a new 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 enable users to increase seal strength, improve aesthetics and broaden the processing window.
The FPA-4500 was designed specifically for sealing pouches with up to 4.5 square inches of seal area. 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 systems incorporate Rinco’s patented PPS0145 seal technology. Each FPA system features a highly rigid actuator capable of rapidly generating the clamp forces required to seal pouches with minimal cycle time. Rinco’s PPS0145 interlocking film sealing technology permits seal patterns with greater surface area. In addition, it allows production of contour-shaped seals. The ultrasonic seal technology also delivers an increase in bond strength over conventional ultrasonics, according to the company.
