Rinco Ultrasonics expands patent technology for ultrasonic sealing for flexible packaging
Rinco Ultrasonics, a US ultrasonic welding equipment supplier, has recently been awarded an additional US patent which complements its previously patented PPS0145 film sealing technology for ultrasonic film sealing of flexible pouch packaging.
The patented technology has resulted in the development of a high-force, high-speed solution which elevates 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 company stated.
The new US patent (US #9272802) was recently granted to Gordon Hull, US Managing Director of Rinco Ultrasonics. "This new development comes in response to customer needs and positions us as a leader in supplying next-generation ultrasonic welding systems for the packaging market," he said.
The new patented technology significantly reduces the need for additional stations on a pouch sealing machine. Rinco's new patented technology takes its already proven barrier seal geometry PPS0145 and incorporates a follow-up cosmetic seal in one stroke at a single station.
Competitive seal offerings have been unable to meet the needs of packaging applications that require sealing through the top of the pouch. Competitors have relied on a separate heat seal station to create this "cosmetic" seal. Rinco's new patent allows for a wide 4mm barrier seal and in some applications up to 20mm of cosmetic seal, which eliminates the need for a follow-up heat seal station and subsequent cool station.
"This is a game-changing development which delivers major efficiencies for the flexible pouch packaging market," said Hull. "The new technology enables OEMs to remove two stations from a pouch filling machine system which reduces floor space and yields major cost savings."
The new seal geometry, PPS0145 Hybrid, is used in conjunction with Rinco's complete line of flexible packaging actuators that fit most major in-line horizontal or rotary horizontal pouch filling machinery.
All of Rinco's FPA systems are CE certified and IP67 rated thus assuring users and OEMs of high quality and compliance with regulatory directives. Rinco has also developed a Flexible Packaging Actuator that has been modified to handle more caustic materials and cleaning solutions that resist erosion and deterioration, thus increasing its life span and reducing downtime.
Rinco will introduce its patented sealing technology at Pack Expo International 2016, taking place from November 6-9 in Chicago, the US.
