BPA free doesn't mean all plastic though. So we'll have to wait for a YouTuber to helpfully try it out in video to show whether or not they do. But also, this doesn't have to be a purity test - even though I think they probably use plastic inside of their cans because they very studiously avoid saying they don't, less plastic is still less plastic. A very thin layer of liner vs enough plastic to be durable as a bottle is an improvement over the status quo.
Most/all plastic for food use is BPA free at this point.
Looks like elaborate marketing. I think something like 95%+ of metal food containers are lined with plastic to prevent the metal from reacting/leeching into the food. Making some assumptions here but I suspect because the vast majority/all of the aluminum can supply chain is plastic lined that these are as well.
I definitely don't think it invalidates that claim! Aluminum cans afaik are still better in that the amount of plastic used is significantly less and you can recycle the outer shell.
I will admit that I haven't specifically checked on the exact composition of their packaging, but "fuck plastic, we're all aluminum" is a marketing message I have heard from them many times. It's possible that they're making that up, but I would assume they'd get in trouble for lying so blatantly. Maybe that's naive of me.
I don't buy it for environmental reasons, so I've just taken them at their word.
