The device history record (dhr) was reviewed, and no abnormal process condition was present during the manufacturing of the product that could have led to the reported condition.The dhr review showed that all acceptance criteria inspections per established sampling levels were within acceptable limits during the production process.Four decontaminated samples without original package or lot number were received.A sample analysis was performed; as part of the analysis the samples were visually inspected according to product specifications.The sample presented a split in the section of the small rib thereby confirming the reported issue.The root cause that was determined for this issue was a problem that occurred during the forming process in which the forming tool reaches a high temperature.Due to properties of the material, the heat is concentrated at the point of contact with the film and not dissipated throughout the rest of the tooling therefore it does not balance out.This may cause the film to overheat and could potentially affect the strength of the material.As a corrective action the material used for the plug assists was changed; the difference in this change is its properties, the heat stabilized around the tooling (not only the contact point with the film) having a lower impact on the film forming process.An engineering test request (etr) was performed to determine the best temperatures to form the lite glove with the new forming tool using the newer, improved material.After the etr was approved, validation was performing to confirm the proposed parameters and ensure the quality of the product.A formal corrective and preventative action was implemented as a result.If additional information is received warranting further analysis, the investigation will be resumed.This complaint will be used for tracking and trending purposes.
