DDL Quizzler Uncovers Packaging Professionals Extreme Knowledge in the Importance of Extended Shelf Life Validation

Validating Medical Device Packaging for Extended Shelf Ensures Sterility

Minneapolis, MN, September 25, 2008 --(PR.com)-- http://www.testedandproven.com/ -- DDL, leader in medical device package and product testing announced that, via findings from their September Validation for Extended Shelf Life Quizzler, nearly 100 percent of the medical device packaging engineers who responded understand the importance of medical device package validation testing for extended shelf life.

“We are pleased to have learned that the packaging engineers who participated in our September Quizzler are aware of the requirements for validating the extended shelf life of medical device packaging,” Patrick Nolan, COO of DDL, stated.

The government requires that all sterile medical device products claiming a shelf life or expiration date must have data to support the claim and their packaging must also withstand the same shelf life capability.

“Without proper evidence to support a claimed shelf life capability the product could be recalled by a regulatory body which could significantly delay product introduction to the market,” Nolan said.

Before validating a medical device for extended shelf life, several questions must be answered:
1. What types of packages are we validating?
2. What type of expiration date do we want?
3. Which strength and integrity methods do we use?
4. What are the glass-transition, melt, and heat-distortion temperatures of the package and device?

“All sterile medical device products and their packaging must have data to validate their shelf life,” Nolan said. “The expiration date can range anywhere from 1-5 years with 3 years being the most common.”

Testing for package integrity and sterility is vital to ensuring that there was no loss in package integrity due to the aging study. Generally speaking, ASTM standard F88 is used for strength testing and F1929 is used for integrity testing. Dye leak testing is commonly done on thermoform trays and bubble leak testing is performed on pouches.
