"Milk is a universal and indispensable product. Going along with the modern tendency to popularize healthy lifestyles and recognizing the importance of environmental protection, we suggest that this product, serving all peoples well since times immemorial, should be super-popularly served in aluminum cans. Their advantages include light weight
and strength, aesthetical appearance and compactness. Aluminum cans fully preserve the natural taste and quality of the product and are easily opened. Because of the new design of the packaging, milk may not be just served at home but also taken along anywhere."
