I wonder if the QA standards are too high for throwaway goods.
Is a soda bottle a high-precision moulding that needs super-precise tolerances? And if so, are there ways to redesign this to reduce the constraints?

Fwiw they do need fairly tight tolerances otherwise the cap won’t seal and the product will leak or spoil.
Size tolerance, the way plastic flows through the molding equipment, temperature at which its blown, how much shit leeches into the beverage, how strong the resulting container is, all that factors in.
Plastics are a complex technology and people are optimizing what we can do with them as across every dimension much as possible
