A six-pack of aluminum cans is convenient. One of the reasons is the lightness of cans compared to other beverage containers. In fact the number of cans per pound of aluminum has gone from about 23 in 1975 to about 33.10 today. Again, this helps us to conserve resources and energy even more. Another factor in the success of the aluminum can is how fresh it keeps its contents.
Nothing chills faster or keeps beverages fresher for longer than the amazing aluminum can.
