On June 3, PTI welcomed pharmaceutical and life science professionals to an exclusive Container Closure Integrity (CCI) Training Day in Paris, France. The event brought together industry experts, partners, and attendees for an engaging day focused on advanced CCI technologies, regulatory guidance, and practical applications. Participants had the opportunity to explore deterministic test methods including Vacuum Decay, MicroCurrent HVLD, and Helium Technology through both technical presentations and hands-on demonstrations. Discussions covered critical topics such as USP <1207>, USP <382>, Annex 1 compliance, method development, and the role of CCI in ensuring sterile product integrity. The Paris event is part of PTI’s global training initiative, aimed at advancing industry understanding of package integrity testing and promoting best practices in CCI. We thank all who attended and contributed to the event’s success, and looking forward to hosting more training sessions throughout the year.
