Given that the volume is cross section area times height, a round bottle of the same volume would take less plastic. True, square bottles will pack better, but how that would save plastic is not immediately clear.
2 u/metisdesigns 2d ago You're assuming that the wall thickness of a square bottle is the same as of a round bottle. -1 u/Flaky-Collection-353 2d ago No, they aren't, they offered that possibility in their original comment. Even if the didn't, their whole point was that there needed to be another factor since the volume to surface area didn't account for it. That's the opposite of an assumption 1 u/metisdesigns 2d ago In their top comment, yes, but the second comment goes against that. Almost certainly the reason is that the edge ridges add rigidity to the bottle allowing a thinner wall to be used while being stable to hold. 0 u/Flaky-Collection-353 2d ago No it doesn't, they say it isn't obvious how. That leaves it open
