Today the product range is divided between the ratioSystems® GmbH | industrial solutions (sealing gaskets and profiles with emphasis on cell rubber products and extruded polyethylene profiles) and the ratioSystems® intelligent solutions GmbH (plastic cases and customized packaging solutions).

Located in the north-west of Germany - in the beautiful old Hanse town of Lüneburg - we do not only enjoy pleasant surroundings but also fast connections to important German industrial regions like Hamburg and Berlin.


Our company slogan


Since its formation in 1997 the slogan "Faster, better, different" has been a guiding principle in the company's processes und development. In our everyday work we try to realize it by offering competent advice, careful planning and quick implementation. Instead of standardized dispatch we put a highly customer-centered service to the fore.


We are constantly optimizing our work processes. Every customer should get their optimal product solution as fast as possible, on a constantly high quality level and every step on the way - from bidding to the consignment of goods.


Thanks to many years of experience in both sectors: sealing gaskets and profiles as well as cases and packaging solutions we are able to develop customized solutions of all kinds. In both areas we focus on innovation, flexibility and creativity. Customized solutions are our standard.


While product quality is one important part in our work we also aim for the best surroundings possible - from a fast service to the proper packaging and labeling. If you have cause for criticism you are welcome to contact us. We are constantly striving for improvement.
