Difference between PS,PET,PP

Many friends don't know the difference between plastic covers of different materials used for disposable aluminum foil container. We're going to make it clear this time.

PS：Applicable temperature-20℃~80℃，non-microwavable.Density 1.045g/cm³，light transmittance90%，tensile strength 60MPa.Poor flexibility(4%), easily scratched.

PET：Applicable temperature-40℃~50℃，poor heat resistance，good low temperature performance,non-microwavable.Density1.38g/cm³，light transmittance92%,tensile strength 45MPa，recyclable, middle wear resistance,better flexibility(200%). 

PP：Applicable temperature-14℃~120℃，high temperature resistance,microwavable,the only microwavable plastic material.Density0.9-0.91g/cm³,Ultraviolet sensitive,tensile strength 30MPa，reusable，good wear resistance，poor wear resistance, the best flexibility(300%-500%)
