PET film oxygen permeance ratio is dropped after crystallization through drawing tropism, modified the barrierperformance.
经过拉伸取向结晶后的PET薄膜氧气透过率获得下降，改善了阻隔性能。

The permeability (P), diffusion (D) and solubility (S) coefficients for polymers and coatings are key parameters that affect a polymer's barrierperformance.
聚合物和涂层材料的渗透系数（P）、扩散系统（D）和溶解系数（S）是影响聚合物阻隔性能的关键参数。
