PET (polyethylene terephthalate) plastic bottle is a widely used plastic bottle, which is usually used to package drinks, food, cosmetics and other items. PET plastic bottle is a kind of food-grade plastic material. After multiple tests and certifications, it is non-toxic and will not cause harm to human body.
However, in the process of production and use, PET plastic bottles may be affected by high temperature, ultraviolet rays and acid and alkali, thus releasing some harmful substances, such as phenol and benzophenone, which will have a certain impact on human health. Therefore, when using PET plastic bottles, don't put the PET plastic bottles in a high temperature environment, so as to avoid the deformation of the plastic bottles and release harmful substances.
Matters needing attention in using PET plastic bottles
1, Don't reuse: Although PET plastic bottles can be reused, it is recommended not to reuse too much, because repeated use will cause the surface of the bottle to become worn and scratched, and these scratches will easily hide dirt and refuse to clean, thus affecting health.
2. Avoid high temperature: PET plastic bottles have low melting point and are easy to deform or even melt in high temperature environment. Therefore, high temperature environment should be avoided during storage and use, and exposure and placement in high temperature places should be avoided as far as possible.
3. Avoid contact with chemicals: PET plastic bottles are soft and easy to react with chemicals, so avoid contact with chemicals, such as acid and alkali, to avoid pollution or deterioration.
4, pay attention to maintenance: when using PET plastic bottles, pay attention to maintenance, avoid long-term not cleaning or improper storage, so as not to lead to bacterial reproduction and odor.
