Light metal packaging for foodstuffs primarily encompasses cans, closures, and aerosols. For cans used in the European Union (EU), the majority are beverage cans with about 45 billion used per annum (pa) compared to ap-proximately 20 billion food cans pa. Metal closures are subdivided into about 20 billion closures for jars and 80 bil-ion crowns for bottles per year. The ILSI Monograph on Light Metal Packaging for Foodstuffs1 contains background information for the reader unfamiliar with this type of packaging. The FACET project (Flavours, Additives and food Contact materials Exposure Tool) was a four-year project that was partially funded by the European Commission within its Framework FP7 Programme. The project ran from September 2008 until August 2012. FACET was coordinated by University College Dublin and it involved 20 research partners from across Europe, coming from academia, industry, research centers, and small- to medium-sized enterprises. Hearty et al. provided an early overview of the project plan2 and Oldring et al.3,4 offered a view of the part of the project plan that dealt specifically with packaging materials. More recently, the use of FACET for assessing exposure to bisphenol A (BPA) from light metal packaging has been reported.5 As the name indicates, the FACET expo-sure tool provides a single platform with the functionality to estimate consumer exposure to three types of food chemicals, namely chemical food additives (“E-numbers”), chemically defined flavoring substances added to foods, and sub-stances used to make food contact materials. A PC-based desktop application, the FACET exposure tool is publicly avail-able and free of charge. The software tool was developed and populated with data gathered throughout the course of the project, with the facility of uploading any additional data that the end-user might have. This article describes how the information was gathered for the light metal packaging portion of the FACET tool.
