EWI UltraThinSeal™ is an affiliate of EWI®, a leading engineering and technology organization that helps manufacturers all over the world become more competitive and bring big ideas to fruition.

In partnership with a global manufacturer of food products, EWI engineers created our unique ultrasonic sealing technology.

Devoted to the entire supply chain of the packaging industry, including packaging end-users, we aim to empower our customers with high-tech, game-changing packaging solutions. Our mission is to facilitate low-risk upgrades to their package sealing capabilities, whether by converting existing equipment or installing the latest high-speed rotary equipment. With our patented EWI UltraThinSeal system, we help our customers achieve significant package cost savings, with ROI that is difficult to ignore. Our customers, in turn, join us in shaping the packaging industry’s future ‒ a future that is flexible, resource-conscious and full of possibilities.
