Ultrasound Technology Analyzes Seal Integrity Accurately and Reliably

PTI’s Seal-Scan and Seal-Sensor test packaging seals in a noninvasive, nondestructive manner both on and off the production line, respectively.

Seal testing doesn’t have to be destructive, time-consuming or subjective. PTI – Packaging Technologies & Inspection’s Seal-Scan and Seal-Sensor equipment use ultrasound technology to test and analyze the seal integrity of pouches and flexible packaging in a noninvasive manner with repeatable and reliable results.

Both the Seal-Scan and Seal-Sensor pulses a noncontact, airborne, ultrasonic focused beam of sound through the seal area. The patented technology produces a linear scan analysis of the seal area in seconds without destroying the packaging to detect defects, such as wrinkles, inclusions, weak seals, channel defects, misaligned seals, and incomplete and missing seals. The technology works on various medical, pharmaceutical, and food packaging, regardless of color, transparency, print, surface finish and porosity.

According to the company, its ultrasound technology is not as destructive as a peel strength test, which can destroy packaging and waste product, and is more reliable, less time consuming, and less costly than manual visual inspection.

“Ultrasound is one of the only technologies that is telling us what the quality of that physical bonded nature of the seal materials are,” says Oliver Stauffer, CEO of PTI. “So it’s really physical inspection of the field quality.”
