Bag Sealer Validation
Application Summary

For sterilized and other sealed pouches and packaging, tears and partially broken seals are not always apparent. To mitigate seal failure and ensure seal integrity, verification of the heat sealing force is
critical, as over/under applied sealing force can cause premature failure of the seal. This application utilizes a pair of LLB130 load buttons to monitor the force applied to pouch during the pouch sealing

Products in Use

FUTEK’s Miniature Load Buttons (LLB Series) paired with the IAA Series Analog Amplifier for feedback into a PLC.

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.
