PP and PET each have their own characteristics and are suitable for different applications.
PP has excellent high-temperature resistance, and can withstand a temperature range of -20℃ to 120℃, and can be directly used for microwave heating; PET has relatively poor temperature resistance, and its general operating temperature range is -40℃ to 70℃.
PP has low transparency, mostly milky white or semi-transparent, and feels soft and flexible; PET has high transparency, close to glass, and has good gloss.
PP has good chemical stability; PET may release harmful substances at high temperatures or with prolonged use.
