One of the world's five major general-purpose plastics, with large production capacity, high cost-effectiveness, high-temperature fusion, strong plasticity, strong adaptability, certain acid and alkali resistance, can be made into FDA food grade, poor oil resistance, and weather resistance

Under strong light, the color will change, and HCl gas will be generated during combustion or high temperature conditions (the main material of the first generation plastic bags, which is not biodegradable)
