Investigation results: 4 photos were returned for investigation.
1 actual sample in opened packaging was returned for investigation.
Our quality engineer inspected the returned units and photos, and confirmed the reported complaint but could not identify any manufacturing related defects.
A device history record review was conducted and no quality notification was raised for similar nonconformance during the production of the batch.
Conclusions: there is an indication of adhesive transferred from the top web to the bottom web on the opened seal areas, which was present on the returned sample showing that the sealing process was completed in manufacturing facility.
Therefore, no assignable root cause can be established.
Customer complaint trends are evaluated on a monthly basis.
If the trend of a specific type of complaint warrants a formal corrective action, resources will be assigned at that time.
