Lightweight PET bottles are convenient because they can be crushed into small, squishable pieces. These PET bottles have many good points: they are light, easy to crush when discarding, and use less plastic. On the other hand, the disadvantages are that they make noise or are too thin to be stable. And there may be another psychological drawback.
That is, it might be less tasty than a solid plastic bottle. Studies overseas have shown that water drunk from a flimsy container tastes less tasty than water drunk from a solid, firm container. In the same way, the weight and quality of the container or receptacle can change the perception of taste. Resource reduction is important, but deliciousness would reduce when using lightweight PET bottles.
It means that the weight and quality of the container or receptacle will affect how delicious it tastes. The question is whether to reduce resources and weight or taste.
