Differentiate, upgrade and evolve your brands

SIG MidiBloc, the classic carton, and SIG MidiFit, the differentiating premium pack, are our most popular formats in the family-size segment. Both come in 500ml, 750ml, or 1,000ml volumes and offer a high level of convenience as well as easy-to-open closures.

SIG MidiStyle, the latest member to the Midi-family, adds a stylish twist and convenience to the classic pack. It builds on the success of SIG MidiBloc, while its centrally positioned closure for improved functionality and a shaped corner panel to stand out on the shelf add a modern touch. This format is available in 500ml and 1,000ml volumes.
