In an installation for the treatment of containers, comprising at least one filling station and a packing station for processing film or packaging material blanks and having work components acting upon the packaging material and forming packages, at least one measuring device for dimensional deviations of filled containers, and a control unit for automatically adjusting at least one installation station depending on a dimensional deviation detected, work components in the packing station (P) acting upon the packaging material when the filled containers are packed are automatically adjustable by way of the control unit. In a method for packing filled containers, work components of the packing station acting upon packaging material are adjusted automatically depending on dimensional deviations measured in order to form packages of different dimensions with at least substantially the same packing density.
