I'm OK with this. Or even glass.

According to the interwebs, it wasn't until the 1960's that plastic bottles became popular in the United States, but I don't remember them until the early 80's.

Before then, soda always came in cans with pull-tabs that would slice your toes open at the beach.

As someone who has worked in the beverage industry. Please don't bring back glass. It's so heavy, it's fragile, and it don't stack efficiently. Beer is finally moving to cans a change which has only happened in the last few years. It's easier to move and store, a twelve oz can takes up about 3/5s the space of a 12oz bottle.

I think the aluminium cans have a thin plastic or polymer coating on the inside too, which stops the drink from tasting like metal... so not sure if it's 100% plastic free either.

They do have a liner, here's a video of someone removing the can from the coke:
