The problem is the plastic we see as a uniform material is a chemical cocktail of the polymer, plasticizers, chain extenders, curing agents, lubricators and process aids, stabilizers, colorants and more. 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
