It’s true, and it’s problematic, but the plastic lining in an aluminium can is super thin, since it doesn’t need to be structural. As far as resource use goes, it’s still way better. It’s best to look for improvements, and not to let the search for perfection block you from a marginal gain.

If you’re going to re-use, use glass, where possible. If you’re not, aluminium is still the better choice.

We should have higher deposits on cans and bottles. Here, it’s been pegged at 5 cents since the 90s - it should be more like 25 cents now for cans, or a dollar for glass bottles.
