Pouch seal inspection refers to the process of evaluating the quality of the seals on a pouch or bag. This can be done visually or through mechanical testing to ensure the seals are strong enough to maintain the integrity of the contents within the pouch. This is an important step in the packaging process to guarantee the integrity of the contents and to prevent product contamination or spoilage. The purpose of pouch seal inspection is to ensure that the seals will not break or leak, thereby preserving the quality and safety of the product.

Traditional seal integrity testing methods are unreliable because they miss unseen defects and mistakenly qualify pouches that have visual flaws. One of the most efficient techniques for non-destructive testing of flexible pouch packaging seals is Airborne Ultrasound technology. Seal-Sensor PQX is a non-contact Airborne Ultrasound technology technology to test package seals 100% online.

The Seal-Sensor PQX is a fully automated pouch seal inspection and handling technology. It comes with an integrated conveyor that can be readily connected into a production line. PTI's Seal-Sensor Airborne Ultrasonic technology is used to automatically scan the final pouch seal online at high speed. Seal-Sensor technology is an ASTM Test Method F3004 and an FDA consensus standard for inspecting seal quality.

Seal-SensorTM is an Airborne Ultrasonic Technology that inspects the final pouch seal 100% online and non-destructively. Seal-Sensor is a deterministic, quantitative, quick, and dependable approach for inspecting pouch seals for defects. Seal-Sensor detects incomplete seals, partial or weak areas in seals, and a variety of frequent defects in seals that appear visually acceptable but contain problems that impact product quality, value, and shelf-life. In less than one second, a single linear scan (L-Scan) of the pouch seal delivers a pass/fail result as well as quantitative, traceable data. At high outputs, a quick linear scan of the pouch seal allows immediate seal check/verification of seal quality. Data from tests is generated in seconds.

The Seal-Sensor PQX is a plug-and-play system for checking the quality of pouch seals inline. This simple-to-install system has a modest footprint and a full-screen HMI for displaying test result data as pouches are scanned. Inspection speeds can reach 350 mm/sec. A built-in reject chute swiftly removes flaws from the line, and a built-in stack light makes determining pass/rail outcomes simple.
