Matters needing attention in daily use
Different kinds of disposable plastic tableware have different use conditions, and their temperature resistance and pressure resistance are obviously different. Tang Saizhen said that the use temperature of disposable plastic tableware is usually below 100℃, and the highest temperature is not more than 150℃.
For example, PS foamed tableware is safe to use below 80℃, so it is not suitable for boiling water and microwave heating. PP plastic tableware has good heat resistance and can be used for microwave heating, but it is not suitable for frozen packaging.

Moreover, every substance belongs to organic substances, which will cause harm to human body more or less. Long-term use of plastic tableware containing certain ingredients may even be life-threatening.
