摘　　要：采用具有不同共聚组分含量的PP原料,进行双向拉伸成型BOPP薄膜,并对薄膜拉伸过程中的拉伸力变化,以及薄膜性能进行了测试和研究。结果表明,随原料中共聚组分含量的增大,薄膜的成型拉伸力有所下降,薄膜的拉伸模量、强度等力学性能相应降低,而薄膜的雾度、光泽度等光学性能明显改善。The BOPP film are prepared using PP raw materials with different copolymer content, the stretc- hing forces during film drawing and the film properties are studied. The results shows that with the rising of copolymer content in raw materials, the stretching forces and tensile modulus and strength of BOPP film decreased, while the optical properties of the films, such as haze and gloss, improve significantly.
