Bag Sealer Validation

.

For sterilized and other sealed pouches and packages, tears and partially broken seals are not always apparent. To limit seal failure and ensure seal integrity, checking the heat seal strength is critical, as excessive or insufficient seal strength can lead to premature failure. This application uses a pair of LLB130 load buttons to monitor the force applied to the pouch during the sealing process.

.

How it Works :

  1. In this application, a pair of Miniature Load Buttons is placed so the force exerted on the heater bars by the packaging can be measured.
  2. As the pouch moves through the heater bars for sealing, the bars are forced outward, resulting in the load cell buttons measuring the applied force.
  3. Utilizing two load cells ensures that the heater bars are spread apart evenly and functioning correctly mechanically.
  4. The resulting load cell output is then amplified by the IAA Series Analog Amplifiers for input into the PLC allowing for fault monitoring and pouch seal verification.
