Pouch Seal Quality Testing: Airborne Ultrasound, HVLD Vs. Traditional Testing Approaches Presentation

Oliver Stauffer, vice president of PTI Inspection Technologies, recently gave a presentation during the IFTPS Annual Conference on the topic of Retort Pouch Innovations.

His presentation reviewed common inspection methods for inspecting pouches and airborne ultrasound technology for pouch seal inspection as an in-depth process control tool. Critical issues with retort pouches continue to be seal quality and pouch integrity. Detecting defects early on in the manufacturing process is critical to increasing output, reducing waste, while assuring product quality and shelf life. This presentation provided an overview of Seal-Scan® ultrasound technology and the latest advancements for seal verification and defect detection including delaminations, inclusions, misaligned seals, incomplete seals, insufficient seal width, and many more. Also provides an overview of high voltage leak detection (HVLD) for liquid filled pouches.
