研究开发了一种超爽滑BOPP 薄膜,并对其性能进行了30 d 的跟踪测试。结果表明,超爽滑BOPP 薄膜的拉伸性能、光学性能和热收缩率很稳定;薄膜的摩擦系数低于0. 15,远低于常规产品摩擦系数为0. 25 的要求,并且相对平稳,使得薄膜具有持续稳定的超爽滑性能。

A kind of super slip BOPP film was developed and various properties of the film were tested for 30 d. The results showed that tensile properties,optical properties, and heat-shrinkable rate of the BOPP films are very stable;friction coefficients of the BOPP film are less than 0. 15, which are much lower than that of conventional films,which are 0. 25, and stable too; the BOPP film has sustained and stable super slip properties.
