In Norway, aluminium cans made from anodised and lacquered strip have been used for several years for food products which are comparatively neutral and not very corrosive, such as herring and bristling in oil, kippers, fish balls, etc. They have not, so far, been used for more aggressive products by the Norwegian canning industry because lack of certainty of the behaviour of aluminium in these conditions has militated against approval by the necessary authorities, i.e. the Hermetikkindustriens Laboratorium and Hermetikkindustriens Kontrollinstitutt (the Norwegian Canning Industry Research Laboratory and the Official Quality Control Institute for Fish Products). However, recent investigations show that anodised and lacquered aluminium may have considerable importance in the future as materials for canning aggressive fish foods.
