Sacco was introduced in 1968 by three Italian designers: Piero Gatti, Cesare Paolini and Franco Teodoro. The object was created in the Italian Modernism movement. Being a post war era phenomenon, Italian modernism’s design was highly inspired with new available technology. Post war technology allowed an increase in the processes of production, by introducing new materials such as polystyrene. The idea of mass-produced goods made within an inexpensive price range appealed to consumers. It therefore created the need for a revolution in the creative and manufacturing process. ‘The designer was an integral member of a process that included marketing as well as engineering’. The inspiration left by Corradino D’Ascano’s Vespa design for the Piaggio Corporation in 1946, added value to the essence of the designer. With successful designs, brands could sell more products, and therefore the identity of the designer played an important advertising role. Another important figure of the Italian modernism period was Gio Ponti. Inspired by modernism's art movements, Ponti created new forms of objects. His asymmetrically balanced designs freed the Italian objects form their classic representations. The designer promoted Italian designs on famous exhibitions called 'Milan Triennale': "These exhibitions, organized as early as the 1920s … were responsible for increasing the visibility of Italian design in an international setting". After becoming an editor of the Domus (magazine) in 1947, Ponti contributed to not only Italian design of that time, but also : “the human and creative element in modern industrial design as well as its practical, economic and social benefits."
