Rinco Ultrasonics, Danbury, Conn., has been awarded two U.S. patents for its film sealing technology for ultrasonic film sealing of flexible pouch packaging. Officials from Rinco announced the patents during Pack Expo, held in November in Chicago.
The patents were granted to Gordon Hull, U.S. managing director of Rinco Ultrasonics.
"We believe we've developed a next-generation actuator which shatters the preconceived notion that ultrasonic seals must be unattractive, narrow and straight," Hull says. "The new technology significantly opens the processing window for the ultrasonic sealing process."
The patented technologies include an ultra-narrow, high speed, high-force actuator and a pedestal-mounted high force actuator retrofit system. FPA 4500-S incorporates a simple fluidic muscle design that allows for the high speed and high force build up to meet the needs and demands of 24-hour packaging facilities. The FPA 4500-T pedestal or horizontal mounted welding system allows for a simple bolt-in replacement of current heat seal stations or for use by OEMs as a purchased unit that gives them multiple options for customers' product and pouch filling needs.
These systems have been designed to fit on most major in-line horizontal or rotary horizontal pouch filling machinery.
