# Accelerated Aging: Extend Packaging Shelf Life to 5 Years > Extend medical device packaging shelf life up to five years with accelerated aging studies from LSO. Validate longer, faster, and smarter. Source: https://lso-inc.com/news/accelerated-aging-shelf-life/ --- NewsOctober 30, 2025 ![Packaging-Expired](https://lso-inc.com/api/media/file/Packaging-Expired-3.jpg) For medical device manufacturers, packaging shelf life is more than a printed date — it’s a measure of compliance, stability, and product confidence. Most sterile packaging validations establish a **two-year shelf life**, but that’s often a conservative starting point. With **accelerated aging studies**, manufacturers can often extend that shelf life to **three, four, or even five years** — without repeating a full validation. > “We routinely help customers extend packaging shelf life to five years with new accelerated aging data,” says **Alan Evans**, Packaging & Validation Manager at Life Science Outsourcing. “The science supports it — and regulators recognize it when the data and documentation are sound.” ## **Understanding Accelerated Aging** **Accelerated aging** is a controlled laboratory method that simulates long-term storage in a shorter timeframe. Governed by **ASTM F1980**, it defines how temperature and time can model real-time aging effects. For every **10°C increase in temperature**, the rate of material degradation roughly doubles — allowing engineers to simulate years of storage in weeks. **Example:** A study conducted at **55°C for 6 weeks** can represent **one year of real-time aging** at 25°C. By extending the study duration, you can generate valid data for **three, four, or even five years** of equivalent shelf life. ## **Why Extend Shelf Life?** Extending shelf life through accelerated aging provides both technical and strategic benefits: - **Reduce testing frequency and costs** by avoiding redundant validations - **Maintain product availability** without downtime tied to validation cycles - **Simplify documentation** by building on existing validation data - **Support longer logistics windows** for global distribution - **Demonstrate long-term compliance** under **ISO 11607-1/2** and **FDA 21 CFR part 820** In other words, shelf-life extension is not just about testing — it’s about **operational efficiency** and **regulatory foresight**. ## **How the Process Works** Extending shelf life through accelerated aging follows a structured, data-backed approach: 1. **Review Existing Validation Data** Confirm that your packaging configuration, sealing parameters, and sterilization method remain unchanged. 2. **Define Target Shelf Life** Decide whether to extend to three, four, or five years based on your business and regulatory needs. 3. **Perform Accelerated Aging per ASTM F1980** Conduct a new aging study using controlled temperature and humidity to simulate the additional years. 4. **Conduct Post-Aging Integrity Testing** Verify sterile barrier integrity with tests such as: 5. - **ASTM F88** — Seal Strength - **ASTM F1929** — Dye Penetration - **ASTM F2096** — Bubble Leak - **ASTM F1886** — Visual Inspection 6. **Document and Justify** If all acceptance criteria are met, update your validation report, product labeling, and technical documentation accordingly. ## **When Shelf-Life Extension Is — and Isn’t — Possible** **You can extend shelf life when:** - Packaging materials, sealing process, and sterilization method are unchanged - Original validation data and reports are traceable and compliant - No packaging or integrity issues have been observed **You cannot extend shelf life when:** - There have been material, process, or sterilization changes - Original validation data is unavailable or incomplete - Prior aging studies failed to meet acceptance criteria ## **Related Reading: Extend Expiration by Two Years Through Revalidation** If your current packaging validation is approaching expiration, you may not need accelerated aging right away.
