One benefit of this non-plastic packaging is there’s no microplastic pollution which might become a much bigger problem in the future. Not particularly useful from a CO2 perspective tho.

There’s probably better alternatives tho, I’ve seen some made from fungi, which I think are even water resistant and not just oxygen resistant like this milk thing, and then there’s aluminium, but that’s not transparent.

Edit: Btw, I know of “transparent aluminum” (like in Star Trek lol!) but that’s a ceramic, no plastic properties.
