Package Testing for Medical Devices & Pharma Products

The purpose of package testing is to ensure that packages are able to withstand the typical events associated with distribution, handling and storage without defect and loss of sterility.

Our package testing services evaluate the strength and integrity characteristics of a packaging system before and after, simulating the anticipated conditions that the system may undergo. This combination of simulation and evaluation is used to validate package compliance with ASTM, ISO, ISTA and other accepted industry standards.

DDL offers full-service package testing at its Eden Prairie, MN and Irvine, CA lab locations, and select package testing capabilities in its Edison, NJ lab.

DDL provides stability storage space for products requiring environmental conditions based on ICH Q1A guidelines as well as customizable storage conditions. Our facilities contain over 38,000 cubic feet of storage space that have been validated for long-term and short-term shelf life studies under various temperature and humidity requirements.

DDL specializes in testing medical devices such as luer fittings, syringes, needles, catheters, guidewires, surgical sutures, cannulae and tracheal tubes. DDL tests to ANSI, ASTM, IEC, ISO, JIS, EN and other industry standards.
