100% Online Pouch Seal Inspection

Seal-Sensor™ is an Airborne Ultrasonic Technology that inspects pouch seals non-destructively 100% online for defects. Seal-Sensor detects incomplete seals, partial or weak areas in seals, and common seal defects that affect product quality and shelf-life. A single linear scan (L-Scan) of the seal takes less than one second and produces a pass/fail result as well as quantitative, traceable data.

PTI is working closely with industry leaders in sealing equipment to integrate Seal-Sensor technology for immediate seal check and seal verification.
