We rely on steel packaging for our food to be in durable, tamper resistant containers. You may not realize it, but you probably use at least one steel can every day. You may hear them called tin cans, metal cans or aluminum cans but most food cans are truly made of steel. Steel cans package a variety of products, including fruits, vegetables, soups, sauces, meats, juice, pet food, cleaning products, shoe polish, paint and coffee. Steel cans are also something else— recyclable.
