Yes, aluminium can be used for the contact with food following some guidelines, as reported by Italian Ministerial Decree 18 April 2007 no. 76. Aluminium is safe if it comes in contact with food for less than 24 hours at room temperature or for more than 24 hours at cool temperature. In alternative, at room temperature and for more than 24 hours, aluminium trays can only contain: cocoa, chocolate, spices, coffee, sugar, cereals, non-fresh pastries, bakery products, confectionery or baked goods, dried legumes, fruit, mushrooms or vegetables.

Aluminium is 100% recyclable and retains its properties indefinitely, so it can be used to produce new packaging solutions or applications. Thanks to its properties, more than 75% of all the aluminium ever produced is still in productive use today.
The recycle of aluminium allows a high energy saving compared to primary production, and a reduction of CO2 emissions.
