Packaging Integrity Testing for Pharmaceuticals and Medical Devices
Packaging integrity testing is crucial for ensuring that the packaging of pharmaceutical products, medical devices, or other sensitive goods is robust and capable of protecting the contents from external factors. Tailor testing methods based on specific requirements, materials, and intended use. Regular testing is essential, especially with changes in materials, processes, or formulations.
Common Methods for Packaging Integrity Testing:
-
Visual Inspection:
Purpose: Detect visible defects in packaging.
Procedure: Skilled inspectors visually examine for damage or imperfections.
-
Leak Testing:
Purpose: Identify leaks in packaging.
Methods: Dye Penetration, Bubble Emission, Pressure Decay Tests.
-
Container Closure Integrity (CCI) Testing:
Purpose: Ensure integrity of seals and closures.
Methods: High Voltage Leak Detection, Vacuum Decay Test.
-
Microbial Ingress Testing:
Purpose: Assess packaging's ability to prevent microorganisms entry.
Methods: Microbial Challenge Test.
-
Mechanical Testing:
Purpose: Evaluate packaging's ability to withstand mechanical stresses.
Methods: Drop Test, Vibration Test.
-
Accelerated Aging Tests:
Purpose: Predict long-term performance through exposure to accelerated aging conditions.
Methods: Temperature and Humidity Chambers.
-
Seal Strength Testing:
Purpose: Assess strength of seals in pouches or blister packs.
Methods: Peel Test.
-
X-ray Inspection:
Purpose: Detect defects inside packaging without physical opening.
Procedure: Use X-rays to inspect contents and identify potential issues.
