What material are most beverage cans made of ?

How many beverage cans are produced in the world each year?

The key development for storing beverages in cans was the interior liner, typically plastic or sometimes a waxy substance. Why was it necessary?

What advantages did cans have over glass bottles for distributors?

What advantages did cans have over glass bottles for consumers?

What a can-opening method did Ermal Fraze devise in 1959 that would come to dominate the canned beverage market?

In the mid-1970s, the push-tab was a raised circular scored area used in place of the pull-tab. It needed no ring to pull up. Instead, the raised aluminum blister was pushed down into the can, with a small unscored piece that kept the tab connected after being pushed inside. Why did they never gain wide popularity?

The safety and litter problems were both eventually solved later in the 1970s with Daniel F. Cudzik's invention of the non-removing "Stay-Tab". The pull-ring was replaced with a stiff aluminum ______________ , and the removable tab was replaced with a pre-scored round tab that functioned similarly to the push-tab.
