Special considerations of using metals as FCMs

1 Special precautions related to the use of uncoated metal foodstuff packaging 

For dry food packs and food oils, the main precaution that has to be taken is that the products are free of water. The tinplate surface provides significant protection but localised free water can induce corrosion under certain circumstances leading to contamination of the foodstuff, particularly if there are corrosive components present in the foodstuff. The packaging supplier should ensure that the food packer is aware of these limitations, but in practice problems with such packs are very infrequent.
