Additional information: a review of the device history record (dhr) was not performed during this investigation as the lot number was not received with the complaint.All dhrs are reviewed and approved by quality prior to release of product.Since a lot number was not provided information such as the test results, quantity manufactured, and date of manufacture could not be determined.There were no samples received with this complaint therefore an examination of the reported condition could not be made.The product is manufactured using a dispense of contents and both horizontal and vertical sealing processes.As the machine moves the materials, the side seals are created using another bar sealer.The materials are sealed and cut apart to make four separate pouches during a cycle.The sealers are set up to seal the liners together as they run vertically through the line.This allows for the contents to be dispensed and the pouch seal to be completed around it.An investigation into activities associated with the manufacture of the product showed that the material alignment is the most likely cause of the issue as described.If the material is not lined up correctly it can cause a weak seal, as there would not be enough material to complete a full seal.It is not always possible to immediately see the issue as one of the materials is clear.It has been determined there are indicators within the manufacturing process which will assist in verifying the materials are lined up correctly.It is also important to note that a series of tests are performed during every lot of production.A pouch with any issues would be rejected at this time and the machine adjusted.The results of the manufacturing facility investigation were able to identify the most probably cause is associated with the manufacturing process.A quality alert has been issued for awareness to some indicators of mis-aligned material.A corrective and preventative action (capa) has been opened to verify the root cause and determine actions to prevent recurrence of the issue.The manufacturing site will continue to trend this issue for future occurrences as part of the complaint review process.
