Expert Guidance. Practical Solutions.
Complex packaging and pharmaceutical programs require more than testing. They require informed technical decisions, the right strategy, and an understanding of how testing and regulatory requirements fit together.
DDL’s consulting services provide practical, science-based guidance to help medical device, pharmaceutical, and combination-product teams solve technical challenges, reduce risk, and move programs forward with confidence.

DDL helps medical device and other regulated-product manufacturers develop packaging strategies, navigate ISO 11607 requirements, troubleshoot packaging and sealing challenges, and prepare for successful verification and validation.

Led by Jay Zaki, Principal Engineer, DDL’s packaging consulting combines engineering expertise with decades of package testing experience to help teams make sound, practical decisions.
Jay brings extensive experience in medical device packaging, package development, testing, and validation. At DDL, Jay works with manufacturers to develop effective packaging and validation strategies, navigate ISO 11607 requirements, select appropriate test methods, and address packaging challenges throughout the product lifecycle.
