According to the World Health Organization, 30% of food in developing countries is lost due to lack of packaging. Therefore, proper packaging and packaging contribute to food preservation, resource savings and waste reduction. Because of aluminum’s resistance to corrosion, it is considered safe from a health point of view and does not leak substances that spoil food or drinks, so it is used to produce cans for storing drinks, food and oils, and aluminum foil is used to preserve pharmaceuticals and food, and since aluminum containers are light in weight, this means saving fuel when transporting. The American Science magazine indicated that the United States of America alone produces 300 million aluminum cans per day, and the weight of the can has become 14 grams after it was 20 grams in the sixties of the last century, and engineers are still looking for ways to reduce the amount of material needed to manufacture the can with Retaining its outstanding performance, reducing the weight of the can by 1% would save approximately $20 million annually in the price of aluminum and make it easier to “gnead” the empty can by hand for recycling
