In the first half of the 20th century, producers of coffee substitutes, tea, and coffee used high-quality metal packaging. They promoted their products by designing boxes with recognizable brand logos, which they also featured in advertising campaigns.

‘Franck’, the largest Croatian factory, processed chicory into various coffee substitutes and mixed them with grains to create beverages reminiscent of coffee in both aroma and taste.

In 1960, Franck began producing coffee, initially packaging it in tin boxes, and later in multi-layered bags and glass jars with plastic lids. The design of the packaging and promotional materials was created by designers working with ‘Ozeha’, one of the first and largest advertising agencies in Croatia and the former Yugoslavia, which operated from 1945 until the mid-1990s. In the 1950s and 1960s, Ozeha’s most advertised products included the Divka coffee substitute by Franck and the very popular Kneipp brand.

The oldest milk packaging in Croatia were metal cans—iron, tin-coated, and aluminium—used to deliver milk to customers. From 1952 onwards, one-litre glass bottles, which offered better protection for the milk, became standard packaging for pasteurized milk in larger cities. The era of UHT milk began in 1963, when it started being packaged in Tetra Pak cartons. The first such packaging line was installed at the ‘Dukat’ factory.
