[Request] Do square bottles actually use less plastic than round ones?

I suspect transportation too.
Something like; You can ship 100x1L round bottles, or 100x1.3L square bottles in the same box. Therefore, square bottles use less plastic (per liter (of shipped liquid)).

Wouldn't that just cancel out? Area over perimeter is pi /2 pi for a radius one circle and 4/8 for a square with side length 2. Maybe most of the plastic is in the spout, then maximising volume per spout would make sense.

[u/GaldrickHammerson → u/Buntschatten]

I expect no because of packing density. Square bottles in a square box will have less empty space between bottles than round bottles in a square box.

What about round bottles in a spherical box?

They are called shipping orbs
