Paper sacks were first introduced in Austria in the late 19th century. They were made of coated paper and were used to store and transport various goods. The sacks were produced by a number of companies, including the Austrian Paper Sack Factory and the Wiener Papierverarbeitungs- und Vereinigungs AG. In the early 20th century, paper sacks began to be used for packaging food, and by the mid-20th century they were the most common type of sack used in Austria. Today, paper sacks are still used for a variety of purposes, including packaging food, transporting goods, and storing materials.
