摘　　要：添加自制爽滑母料制备流延聚丙烯(CPP)热封膜,在存储期30d时测得其表面张力大于38mN/m,非电晕面的摩擦系数稳定在0.1~0.2,电晕面的摩擦系数为0.5,纵向拉伸强度达到60 MPa,横向拉伸强度达到27 MPa,薄膜具有高表面张力、较低摩擦系数、较好的力学性能。同时测得其初始热封温度、热封强度和光学性能均优于国家标准,在存储期内薄膜的综合性能稳定。Cast polypropylene （CPP） heat sealing film was prepared by adding the homemade smooth masterbatch. The surface tension of CPP heat sealing film is more than 38 raN/m, and the non-corona surface friction coefficient is stable at 0. 1-0. 2, and corona surface is 0. 5, and the longitudinal tensile strength reaches 60 MPa, and transverse tensile strength reaches 27 MPa in the storage period of 30 days. The films have high surface tension, lower friction coefficient, and better mechanical properties, at the same time its initial heat sealing temperature, heat sealing strength and optical properties are better than the national standard. The comprehensive properties of film are stable during the storage period.
