Recognizing the limited availability of fossil resources market players and producers take increasingly have to into account sustainable materials for packaging. Ecological films such as made from hemicellulose, could become an efficient means for packaging based on regenerative resources. Such materials are not only biologically biodegradable but can also be utilized in a variety of ways. However, their actual market potential still requires exploration. So far, dedicated application domains for hemicelluloses films are not known. In particular, sectors need to be identified while taking into account product features. In this thesis the market potential is determined based on interviewing relevant market players from the food industry in the German speaking area as a potential sector. Their data allows identifying product-relevant properties, as well as sectors or industries creating film products. Secondary data leads to application chances and barriers, and serves as input for calculating the actual market potential. For the food industry the market potential has been calculated 927t/a for the 26 surveyed companies. 567t/a refer to convenience food, 278t/a to cheese and dairy products, 82t/a to meat and sausages. The high oxygen barrier of the films is a key issue for the food sector, while the high water vapor permeability and the lack of sealing capabilities are considered major limitations. Once the films could be heat sealed the market potential would increase significantly from 927t/a to 30.328t/a in the food industry. Perforating adds 77.038t/a for fruits and grocery. Heat sealing indicates how further developments could trigger higher market potential than the one currently identified.
