Packaging and Shelf-Life Verification Report

​

Summary

The Packaging and Shelf-Life Verification Report documents the testing and validation of your medical device packaging system and shelf-life claims. This report provides evidence that your packaging maintains device sterility, integrity, and functionality throughout the claimed shelf-life under specified storage and transportation conditions.

​

Why is Packaging and Shelf-Life Verification Reporting important?

Packaging and shelf-life verification is essential for medical device safety as inadequate packaging can lead to contamination, device degradation, or loss of functionality before use. The verification report demonstrates that your packaging system protects the device throughout its intended shelf-life and that expiration dating is scientifically justified.

This documentation is required for regulatory approval as it provides evidence that your device will remain safe and effective until its expiration date. Without proper packaging and shelf-life verification, you cannot establish valid expiration dating or demonstrate that your device maintains its essential performance throughout its claimed shelf-life.

​

Understanding Packaging System Requirements

Sterile barrier system design must maintain sterility throughout the device’s shelf-life while allowing aseptic presentation at the point of use. Consider material selection, seal integrity, microbial barrier properties, and compatibility with sterilization processes.

Protective packaging must protect the device from physical damage, environmental conditions, and contamination during storage and transportation. Consider shock, vibration, compression, temperature, humidity, and light protection requirements.

Labeling integration ensures that all required labeling information remains legible and adherent throughout the shelf-life. Consider label materials, adhesives, printing methods, and environmental resistance.

​

Planning Packaging and Shelf-Life Studies

Study design should address all critical packaging functions and potential failure modes. Consider package integrity, sterile barrier maintenance, device protection, and labeling durability under relevant environmental conditions.

Aging conditions should represent or accelerate the storage and transportation conditions your device will experience. Use real-time aging at recommended storage conditions and consider accelerated aging studies to support initial shelf-life claims.

Test intervals should provide sufficient data points to characterize packaging performance over time. Plan testing at time zero, intermediate time points, and at the claimed shelf-life endpoint.

​

Conducting Package Integrity Testing

Seal strength testing verifies that package seals maintain adequate strength throughout the shelf-life while still allowing easy opening. Test peel strength, burst strength, and creep resistance as appropriate for your package design.

Microbial barrier testing demonstrates that the sterile barrier system prevents microbial ingress throughout the shelf-life. Use appropriate test methods such as microbial challenge testing or dye penetration testing.

Physical integrity testing verifies that packaging materials maintain their protective properties throughout the shelf-life. Test for material degradation, dimensional changes, and barrier property maintenance.

​

Shelf-Life Validation Testing

Device functionality testing verifies that the device continues to meet all performance specifications throughout the claimed shelf-life. Test all critical performance parameters and safety functions.

Sterility maintenance must be verified for sterile devices throughout the shelf-life. Use sterility testing or bioburden monitoring as appropriate for your device and sterilization method.

Material compatibility testing ensures that packaging materials don’t adversely affect device performance or safety through leachables, extractables, or other interactions.

​

Accelerated Aging Studies

Aging protocol development should follow established guidelines such as ASTM F1980 for accelerated aging of sterile medical device packages. Establish appropriate temperature and humidity conditions based on your device’s storage requirements.

Correlation studies may be needed to demonstrate that accelerated aging results correlate with real-time aging. This is particularly important for novel materials or complex devices.

Statistical analysis should provide confidence that accelerated aging results support your shelf-life claims. Use appropriate statistical methods to analyze aging data and establish shelf-life endpoints.

​

Environmental Testing

Transportation testing simulates the environmental stresses your packaged device may encounter during shipping and handling. Include vibration, shock, compression, and temperature cycling as appropriate.

Storage condition testing verifies packaging performance under various storage conditions including temperature, humidity, and light exposure that may occur during distribution and storage.

Extreme condition testing evaluates packaging performance under worst-case environmental conditions that may be encountered during transportation or storage.

​

Example

Scenario: You are developing a sterile surgical instrument with a 5-year shelf-life claim. The device is packaged in a Tyvek/film sterile barrier system with protective outer packaging. The device must maintain sterility and functionality throughout the shelf-life under specified storage conditions.

Your packaging and shelf-life verification includes real-time aging studies, accelerated aging per ASTM F1980, package integrity testing, and device functionality testing. Results support a 5-year shelf-life with appropriate storage conditions and demonstrate packaging system effectiveness.
