Problems solved by technology

[0002] Plastic is an indispensable product in life. Most of children's toys are also made of plastic products. However, as far as the plastics in the market are concerned, most of them contain a large amount of carcinogens and their stability is weak. Once they are used for a long time Finally, the leakage of harmful substances has occurred, especially for children, which has a huge impact, so there is an urgent need for an environmentally friendly plastic that can be used by children
