Ultrasonic Pouch Sealer Gives Double Seal Strength
A new ultrasonic pouch sealing system by Sonics (sonics.com) features a seal pattern that nearly doubles seal strength on retort pouches. Focusing on sealant compression and rate of evacuation, the technology reduces film stress and increases seal strength by keeping greater quantities of sealant in the bond area.
For applications where maximum seal strength is required, Sonics offers new technology wherein the tools are engineered to reduce stress by creating a specific flow path that restricts the movement of the sealant during the weld process.
