🥫 Metal is one of the most common food packaging materials on the market. From containing soda bubbles to preserving bean texture, metal is known for its strength, protective properties, and ability to preserve food over extended periods. It is also a permanent material that can be infinitely recycled. Today, aluminum and steel remain the dominant metals used in cans, trays, lids, and foils.
☝️ However, some metals raise safety concerns due to the migration of metal ions into foods and beverages. Coatings applied to the inside of cans to prevent direct contact between metal and food may contain harmful chemicals (including the now infamous BPA) that migrate into food. Often, the exact composition of these coatings remains unknown to the public.
