Thank you, good read! I just remember finding out a while ago that it was better than the environment (and it does make sense given how little plastic is used), but couldn't find the source again.

With this new information, will consumers swing over to milk bags? Bagged milk is sold only in four-litre allotments in Canada, which may be too much for some consumers, leading to unconsumed or spoiled milk. This would wipe out any environmental benefits.

Precisely my concern above hahah, I don't see why they can't be sold individually with a little stamp on them stating the brand, the quantity and the percentage. We don't really drink milk, we only use it for cooking and hot beverages.
