shelf life [10,13]; the latter two groups mostly in form of scenario studies. Recent studies have pointed out the importance of considering packaging functions for packaging LCA [14,15]. A recent study [16] presented a systematic theoretical framework to define key packaging functions and their relevance for sustainable development. However, there is a lack of related studies for specific food packaging applications. The current study uses a function-driven approach tailored to yoghurt packaging to define the functional unit. Three key functions for yoghurt packaging are expressed and quantified, in terms of function related properties of the packaging samples under study, based on application specific material properties. Material properties include: yield strength, young’s modulus, yield strain, oxygen and water vapor permeation coefficients. Cradle to gate non- renewable energy use (NREU) and greenhouse gas emissions (GHG) are normalized to several packaging functions provided by the packaging material in yoghurt packaging.
