Effect of Laminate Structure and Morphology on Fracture Mechanics and Seam Strength of Sealed Seams

摘要

1. Seal seam strength of ultrasonically sealed seams often are tower than for conventional (CS) sealed seam 2. Seal seam morphology and topology is characteristic for ultrasonic sealing and caused by melt flow and internal heating 3. Seal seam morphology of ultrasonically sealed seams causes lower seam strength leven (depending on sealant properties) 4. Seal seam topology affects the stress distribution in the seam.
