Plastic raw materials are defined as a type of synthetic or natural polymer compound that can be molded into various shapes and ultimately maintain its shape, or a plastic material product.

Plastic is an important organic synthetic polymer material with a wide range of applications. However, the "white pollution" caused by discarded plastics is becoming increasingly serious. If we understand the detailed classification of plastics, it can not only help us use plastic products scientifically, but also facilitate the classification and recycling of plastics, and effectively control and reduce "white pollution".
