BOPP薄膜抗静电性能的研究

Development of antistatic properties of BOPP Film

为改善薄膜的抗静电性能,在双向拉伸聚丙烯(BOPP)薄膜中添加一种自制的抗静电母料,并与添加进口抗静电母料的BOPP薄膜进行对比。结果表明:两种抗静电母料在BOPP薄膜的拉伸性能、光学性能、热收缩率和摩擦性能上基本没差异;在抗静电性能方面,不管是电晕面还是非电晕面,新开发BOPP薄膜抗静电性能均优于对比样;新开发BOPP薄膜电晕面的抗静电性能有明显改善,静电半衰期比较平稳,且一个月内的抗静电效果的持续性很好。

This paper describes an antistatic masterbatch developed to add into biaxial oriented polypropylene packaging（BOPP） film to improve the antistatic properties of the film, which is compared with that added with masterbatch imported from Germany. The results show that the friction, tensile, and optical properties of the two antistatic BOPP films are basically no difference as well as heat-shrinkable rate. While the antistatic properties of the newly developed film such as corona and non-corona surface are superior to those of the compared sample. The antistatic property of corona surface of newly BOPP film is improved obviously with stable electrostatic half-life, which can sustain for a month.
