Seal Voids

Blister Pack Seal Voiding, Through Transmission - Application Note 800

Sample & Method

This blister pack was imaged using the THRU-Scan.

Result

The blue areas are locations of signal loss, representing voids which block transmission of the ultrasound through the sample. As these voids become larger, they connect and threaten the integrity of the package by providing a leak path. This seal is nearly compromised.
