Sterile Barrier Packaging: Common Causes of Failures and How to Correct Them

● Quality Control  ● Regulatory/Clinical Affairs  ● Research/Development/Design   Manufacturing

This presentation will provide a brief overview of the types of tests that are available to validate a sterile barrier system. While performing these tests, though not expected, failures can happen. The presentation will also look at common failures within these tests and provide understanding of their causes.


Session Takeaways:
• Packaging attributes and validation testing
• Discovering the root cause of a failure identified during package validation testing
• Tools to assist in determining the appropriate tests for validation
