Why are plastic bottles all round-bottom design? Let's talk about this problem today.

First, the mathematical point of view, cost savings. When the circumference is constant, the circular area is the largest, and the near circle can save raw materials. This is also the reason why the round was first promoted.

Second, the aesthetic point of view, long time ugly. The habit of growing up for a long time is more in line with aesthetics.

Third, the manufacturing angle, the process is simple. Whether it is glass or plastic, the round shape is relatively easy to make, other shapes need to be re-made, and the process is difficult to guarantee.

Fourth, behavioral perspective, easy to use. The round shape matches the human body and is easy to grip.
