Finished Product Evaluation

  •     Inspect preforms for defects such as nicks, warping, or dimensional inaccuracies that could affect blow-moulding and sealing.
  •        Test closures for ovality, liner integrity, seal strength, and application torque to prevent leaks or tampering.

Verification

  •        Verify that preforms, closures, and related materials conform to specifications, recording batch numbers for traceability and reporting any non-conformances to supervisors.

Investigate quality issues
