The safety of aluminium foil as a packaging material is particularly important here.
Aluminium foils are all made from virgin aluminium after alloying and rolling through a number of processes, and are themselves free of harmful substances such as heavy metals. During the production of aluminium foil, a high-temperature annealing and sterilisation process is used, so that no bacteria or micro-organisms can grow on its surface.
The production of aluminium foil lunch boxes and containers is also regulated by strict national and industry standards.
The industry standard "Aluminium Foil Products for Catering and Cooking" has also been published and implemented, providing guidelines for the production, processing and quality assurance of these products, as well as a basis for testing and market supervision of these products, which also includes detailed hygiene requirements
