Alufoil: functional & absolute barrier

- scientific proof by FABES

The results of the study show that aluminium foil of a thickness of at least 6 micron is not only a functional barrier but even an absolute barrier in terms of food contact applications:

'Based on the theoretical evaluation of the experimental data, especially those obtained from permeation experiments performed at 100°C, it could be demonstrated for the laminates containing an Alufoil with a thickness of at least 6 µm that at 100°C the migration limit of 10 ppb will not be exceeded before 30 hours.'

Such severe conditions would never be encountered in the use of a packaging material even under a worst case scenario. The experimental conditions therefore demonstrated unambiguously, and by the resulting scientific data, that an Alufoil layer of at least 6 µm thickness has to be considered an absolute barrier in terms of food contact applications
