Aluminium cans are probably one of the most effective packing tools we have. They are light, they are volumetrically efficient compared to let's say bottles. They can be recycled effectively. Also they keep stuff good longer than plastic. Glass on other hand is heavy, and washing it to food standard requires surprisingly hot water and caustic chemicals. Plus all the care in the handling and extra tooling in handling the bottles.
