    Abstract: A polymeric film has a substrate layer of polyester material and an antistatic layer containing a polyester/polyalkylene oxide copolymer and a salt, the ratio by weight of copolymer/salt being in the range from 0.1 to 100/1. The copolymer is preferably a polyethylene terephthalate/polyethylene oxide block copolymer and the salt is preferably an alkali metal salt. The film exhibits low Surface Resistivity, even at low Relative Humidity.

    Abstract translation: 聚合物膜具有聚酯材料的基底层和含有聚酯/聚环氧烷共聚物和盐的抗静电层,共聚物/盐的重量比在0.1至100/1的范围内。 该共聚物优选为聚对苯二甲酸乙二醇酯/聚环氧乙烷嵌段共聚物,并且该盐优选为碱金属盐。 即使在较低的相对湿度下,该薄膜也表现出低表面电阻率。
