PET bottles have many advantages, but they still have the following shortcomings:
a. First of all, the machine for making pet products is expensive. If you plan to make a pet product, you need a lot of investment in the early stage, and it is not easy to start this work.
b. PET products have a lot of convenience when they are used, but at present, the recycling measures for this material product are still not so good. If PET products are not recycled, they are likely to cause serious harm to the environment. However, as people nowadays become more and more concerned about environmental sanitation issues, they are doing better and better in this respect. In recent years, the recovery rate of PET products has been greatly improved.
c. There is also that although PET products do not cause harm to people's bodies in daily use, in some specific environments, such as high temperature, or strong light, pet still produces some elements that harm the human body. .
