Rettenmaier, J. & Söhne GmbH & Co. KG

As an international systems and technology partner, JRS, J. Rettenmaier & Söhne GmbH + Co KG offers contract manufacturing for market support, special projects and pilot projects. Together, with our customers, we develop solutions tailored to the most diverse challenges and applications. We carry out contract manufacturing in the fields of pharmaceuticals, foodstuffs, animal feed, plastics and other versatile technical applications. The tasks can be implemented individually and promptly in special plants with complete process development in their own machine building.

Newly developed products are manufactured in JRS facilities at several locations in any desired volume. JRS customers have access to already existing facilities and can offer new products faster. Demand fluctuations are buffered by JRS as a contract manufacturer that usually handles several manufacturing orders during the year on the respective system provided. Speed, reasonable prices and an environment that adapts to the constantly changing legal requirements are the decisive basic motivations of customers to make use of outsourcing. In the life sciences areas, the main motivations for working together with JRS are the high regulatory requirements and the high amount of documentation work as well as the high minimum hygienic requirements.
