The Supervisory Board of Gerresheimer has appointed Achim Schalk to the Management Board of the Group. He will succeed Dr. Lukas Burkhardt on November 1, 2025, who is leaving Gerresheimer at his own request to pursue a new professional challenge.

Achim Schalk comes from specialty materials and nonwoven manufacturer Magnera, where he was most recently responsible for business in the EMEIA and APAC regions. The company was formed in November 2024 from the merger of the Health, Hygiene and Specialties division of Berry Global with Glatfelter.

Achim Schalk started his career at automotive supplier Kolbenschmidt Pierburg after completing his studies in economics. After more than 10 years in positions of increasing responsibility in finance and controlling, he held various positions in procurement, sales, product development, and operations at companies within the Berry Global Group, most recently as Executive Vice President and General Manager of the Health, Hygiene & Specialties EMEIA & Asia division, which merged with Glatfelter to form Magnera in November 2024. At Gerresheimer, he will join the Management Board and assume responsibility for the Moulded Glass, Tubular Glass, and Syringe Systems business units.

“Achim Schalk has extensive experience as a manager in large international manufacturing companies with proven expertise in operations, sales, and finance,” said Dr. Axel Herberg, Chairman of the Supervisory Board of Gerresheimer AG. “We are confident that he will successfully drive forward the integration of Bormioli Pharma and the planned growth of the Gerresheimer Group.”

With the appointment of Achim Schalk, responsibilities within the Management Board for the business units will be reassigned. From November 2025, Achim Schalk will assume global responsibility for the Moulded Glass, Tubular Glass, and Syringe Systems business units of the Group. Dietmar Siemssen, CEO of Gerresheimer, will head the Primary Packaging Plastics, Medical Systems, and Advanced Technologies business units.
