Modular production plant and method for producing and / or filling of containers

describes a production system for producing and / or filling of containers and a corresponding method. There are modular processing units with stationary work modules and handling equipment for the handling of containers between a container inlet of the treatment unit and a container outlet of the treatment unit and provided for positioning the containers in the work module. The handling devices are configured such that the treatment units can be replaced individually, and / or there are two identical treatment units are provided at least on which the containers can be distributed selectively. Therefore, the capacity of the production line can be used very flexibly and efficiently.
