FUTEK has introduced a new range of load cells that can ensure the
integrity of seals in packaged products. Pouches or packaging containing
sterilised or sealed products can tear, break or get damaged, which may not be
visible but can lead to spoilage or a compromised product. For manufacturers
and packaging plants to mitigate seal failure and ensure seal integrity, it’s
important to ensure verification of the heat sealing force, as over or under
applied sealing force can prematurely cause the seal to fail.
Seal validation can be done using a pair of FUTEK LLB130 load cells to
monitor the force applied to the pouch during the pouch sealing process. The
manufacturer can monitor and intercept faults, ensuring the integrity of the
In the conceptual diagram above, two subminiature button load cells are placed
to measure the force exerted on the heater bars by the packaging. 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. The two load
cells ensure that the heater bars are spread apart evenly and functioning right
mechanically. The resulting load cell output is then amplified by the IAA
series analogue amplifiers for input into the PLC, allowing for fault
monitoring and pouch seal validation.
