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 for seal integrity testing and seal quality analysis of pouches and flexible packaging. Testing is non-destructive, non-invasive and requires no sample preparation.
The Seal-Scan 525 is a semi-automatic inspection system used for the detection of seal defects, seal characterization and material analysis. Seal-Scan 525 also provides advanced digital imaging software tools for process control which offers in-depth seal quality analysis. Seal-Scan 540 is the online configuration for automated inline scanning of pouch seals, providing rapid real-time result data of pouch seal quality.
Benefits
- 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
- Supports sustainable packaging initiatives due to zero waste
Technology
Pouch seal or package material is placed between ultrasonic transmitter and receiver. 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 seal integrity. Various types of defects, leaking and non-leaking, process-related and random are detectable. Seal-Scan™ 525 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 Opto-Acoustic ultrasonic image of seal structure. Seal-Scan 540 can be integrated into a pouch production or pouch handling line with 100% online defect detection.
