Our history:

In the beginning there was the tube.

We come from the tube, so to speak: The nucleus of CTA GmbH was Albert Kienzle GmbH & Co. KG, a tube manufacturer that also produced rubber solutions and patching tools. In 1996, Kienzle GmbH was taken over by the Tubex Group, one of the world’s leading tube manufacturers. CTA GmbH has been an independent subsidiary since 2005. We are the filling specialists within the Tubex Group and have the experience and expertise to fill chemical-technical products in liquid to highly paste-like form into almost any conceivable packaging.

Our responsibility:

Do something for the environment.

Since our company moved to Ludwigsburg in 2018, CTA GmbH has had its own waste management department. The task of this department is to use all resources as sparingly as possible and to repeatedly examine every process according to environmental protection criteria. The sustainability certificate awarded in 2020, which is based on the calculation method of the Fraunhofer-Institut für Umwelt-, Sicherheits- und Energietechnik UMSICHT (Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT), shows that we are on the right track when it comes to sustainability.
