Marking numbers at the bottom of plastic bottles needs improvement

Plastic bottles have seen a series of negative events such as bisphenol A and plasticizers in the past two years, which has caused people to feel distrustful of plastic bottles and other packaging products. However, plastic bottles are in fact graded, and when used correctly There will be fewer problems. So how to distinguish it? Now if you go online and search, you will find out a lot of articles about the password on the bottom of the plastic bottle to describe the meaning of the number on the bottom of the plastic bottle. However, I believe most people will not understand it. Insufficient understanding of plastic bottles led them to resist using plastic bottles.

In fact, the numbers from 1-7 at the bottom of the plastic bottles do represent different materials, as well as the scope of their use and the need for attention. But this is just like a password, meaning nothing to the average consumer. In this regard, we think it is necessary to improve the traditional logo on the bottom of plastic bottles. Manufacturers are obliged to display the material, scope, and precautions of each plastic bottle at the bottle label through a certain process, and must be clear and understandable. I believe that only this kind of processing will make ordinary consumers more scientific and more assured. It also reduces people's misunderstanding of plastic bottles.
