General performance PET resin is milky white translucent or colorless and transparent, with a relative density of 1.38 and a light transmittance of 90%. PET belongs to the medium barrier material, the utilization factor of O2 is 50~90cm3·mm/(m2·d·MPa), and the utilization factor of CO2 is 180cm3·mm/(m2·d·MPa). The water absorption rate of PET is 0.6%, and the water absorption is small.
