Seal-Scan and Seal-Sensor utilize Airborne Ultrasonic Technology (ABUS) that inspects and analyzes pouch seals non-destructively. Seal-Scan® is a deterministic, quantitative, high resolution method that inspects pouch seals for defects and seal integrity for consistency. Testing is non-destructive, non-invasive, and requires no sample preparation. Seal-Scan® provides advanced digital imaging software tools for process control which offers in-depth seal quality analysis. Seal-Sensor™ inspects the final pouch seal non-destructively 100% online. Seal-Sensor is a deterministic, quantitative, rapid and reliable method to inspect pouch seals for defects. PTI integrates the Seal-Sensor into industry leading sealing equipment for online seal check and seal verification. Airborne ultrasound technology is an ASTM Test Method F3004 and FDA recognized standard for seal quality inspection.
