ABUS (AirBorne UltraSound) - ASTM F3004 - 13 - Seal Quality Inspection


Brand: PTI
Product: SEAL-SCAN 520


Seal Scan

Seal Integrity Testing and Seal Quality Analysis
Seal-Scan® characterizes seals that appear visually acceptable yet possess defects that affect product quality and shelf-life. Seal-Scan® systems utilize non-contact airborne ultrasonic technology (ABUS) for seal quality testing and seal analysis of pouches and flexible packaging. Seal-Scan systems utilize the ASTM Test Method F3004-13, non-destructive test method for "Evaluation of Seal Quality and Integrity using Airborne Ultrasound Technology". Approval of this test method was developed utilizing PTI's ABUS technology.
The Seal-Scan 520 is a semi-automatic inspection system used for the detection of seal defects, seal characterization and material analysis. Testing is non-destructive, non-subjective and requires no sample preparation. Seal-Scan 520 provides advanced digital imaging software tools for process control which offers in-depth seal quality analysis.

- Characterizes overall quality and uniformity of the seal
- Non-destructive solution for process control/quality control/process optimization
- Analyzes seal quality
- Provides statistical sealing trend analysis
- Produces high resolution Opto-Acoustic image of seal
- Replaces visual and/or destructive inspection methods and eliminates subjective results.


Pouch seal or package material is scanned between two focused ultrasonic sensors. Ultrasonic waves propagate through single or multiple layers of bonded materials. Transition through different mediums causes reflection of sound waves and reduces/eliminates signal strength. The level of signal passing through the seal is a function of the quality of the seal. Various types of defects, leaking and non-leaking, process-related and random are detectable. Seal-Scan 520 is capable of producing Opto-Acoustic images as well as detailed statistical analysis by either of two scan modes (L-Scan and C-Scan). An L-Scan is a single linear scan along the X-axis of the seal that provides a line graph of seal integrity. C-Scan produces multiple scans (along X and Y axis of seal area) that provide a high-resolution ultrasonic image of seal structure.
Seal-Sensor is the online configuration of ultrasound technology, which can be integrated into a pouch production or pouch handling line with 100% online defect detection.
