This report presents unit processes for the life-cycle steps 'production of closures, packing, trade and consumer' for food packaging. The different substance and energy flows corresponding to these unit processes are presented where it was possible. In the first section the unit processes for different closures, such as crown caps, twist-off caps, corks and extruded plastic closures are described. Beyond that, for the production of extruded plastic closures the substance flow data are displayed. With respect to packing and trade processes the definition of the system boundaries between packed good and packaging system proved to be very important. In the section 'packing' unit processes for printing, labelling and rinsing (three variants) of packaging are developed and documented with data. For the life-cycle step 'trade' unit processes for commissionning and storing with and without cooling are displayed. The environmental impacts caused by the consumer are basically described by the unit process for rinsing. For this unit process the corresponding data are documented.
