摘　　要：采用3层流延共挤工艺,研究了不同抗静电剂对流延聚丙烯(CPP)薄膜润湿张力的影响,以及电晕处理功率、处理方式对薄膜润湿张力的影响。结果表明,添加牌号为ASPA 2446OB DC的抗静电剂,采用双站电晕处理的方法制得的双面爽滑的CPP薄膜30d后的润湿张力可保持在38mN/m以上,该薄膜既可里印又可热封,可不经复合直接用于低温包装。The influences of different antistatic agent, corona discharge power, and treating technology on wetting tension of three-layer casting polypropylene （CPP） films were studied. When antistatic agent ASPA 2446 OB DC was introduced, the CPP film treated with two station corona could preserve a wetting tension over 38 mN/m after 30 days. This film could be used in both in printing and heat sealing, and could directly be used in low temperature packaging field without laminating.
