Food contact materials
When using aluminium alloys, copper alloys and stainless steel in the food industry, there are rules for the contents of each alloy.
These requirements ensure that there is no significant migration of harmful substances into food. If there is a health risk from using a particular metal or alloy, it cannot be authorised as a food contact material.
In cases of doubt, please refer to your local food safety authorities.
