Problems solved by technology

Since plastic itself does not have antibacterial properties, when it is used as packaging materials such as food and medicine, under the specific temperature and humidity conditions for storing food and medicine, the surface of the plastic is easy to breed microorganisms such as bacteria that are harmful to human health, and the growth and reproduction of microorganisms It will contaminate the stored food or medicine, causing it to deteriorate, mold or even rot; daily necessities such as toothbrushes and tableware are also prone to germs during use, and directly affect human health
