Seal Integrity Tester for Pouches and Flexible Packaging: Veripac 520

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.

Request Information

The Seal-Scan 520 is a semi-automatic inspection system used for the detection of seal defects, seal characterization and material analysis. Seal-Scan 520 also provides advanced digital imaging software tools for process control which offers in-depth seal quality analysis. Seal-Sensor is the online configuration for 100% automated inline scanning of pouch seals.

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
  • Eliminates subjective, variable results of visual and/or destructive inspection methods

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® 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 Opto-Acoustic ultrasonic image of seal structure. Seal-Sensor can be integrated into a pouch production or pouch handling line with 100% online defect detection.
