Onderzoek: Pel-, schuif- en scheursterkte van ultrasoon gesealde folie voor verpakkingstoepassingen

In a study researchers at Iowa State University USA aimed to identify the set of welding parameters that yields the highest weld strengths in six different triple-layer, coextruded polyolefin films. Welds were made using an ultrasonic plunge welding system.
It was observed that energy and weld force had a significant effect on peel strength for the majority of the materials. Low weld energy and low weld force were observed to produce high-shear strength welds for all materials. The highest tear resistance was found with welds created with the highest force and amplitude and at mid-range energy levels. An article about the research was published in Welding in the World.
