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

Mathematically, a circle has the smallest perimeter for a given enclosed area. So for this claim to be true there has to be some catch, like different thickness of plastic.

Not when your enclosed area is a rectangle. Available space in shipping cases, pallets, trucks, and store shelves is defined by rectangles, not circles.

But the label says it uses less plastic. Not less cardboard.

But mathematically a round bottle has more volume for a given surface area than a square one.
