The Role of Packaging in Device Safety
Medical device packaging serves a critical dual purpose: it must maintain sterility and product integrity through the distribution chain while enabling safe, aseptic presentation at the point of use. A packaging failure is not merely a commercial problem—it can directly endanger patients.
Sterile Barrier System Design
The sterile barrier system (SBS) is the minimum packaging layer that prevents the ingress of microorganisms. Common SBS materials include:
- Tyvek-film pouches and trays
- Paper-film pouches (for EO-sterilized products)
- Formed-film lidded trays
- Foil laminate pouches (high moisture barriers)
Validation per ISO 11607
ISO 11607 requires comprehensive validation of packaging systems, including:
- Package integrity testing – Dye penetration, bubble emission, vacuum decay
- Seal strength testing – Peel strength per ASTM F88
- Accelerated and real-time aging – Simulating shelf life under defined conditions
- Distribution simulation – ASTM D4169 or ISTA protocols
Labeling Requirements
Device labels must comply with FDA 21 CFR Part 801 and, for IVDs, 21 CFR Part 809. Key elements include the device name, intended use, lot/serial number, manufacturer information, sterilization indicator, expiration date, and UDI (Unique Device Identification).
