    摘要:

    用表面活性剂聚甘油脂肪酸酯(PGFE)对BOPP薄膜进行表面改性,降低薄膜表面张力,使其具有防雾作用。以聚甘油脂肪酸酯为防雾剂,采用涂布法制备得到PGFE/BOPP防雾薄膜,通过试验测定分析了薄膜的防雾性能,机械性能、光学、透氧、透湿等性能。结果表明:涂布PGFE后,薄膜拉伸强度增大、雾度增大,透光率降低,对氧气、水蒸气的阻隔性提高,其中2%浓度的PGFE涂布后,BOPP薄膜防雾效果,机械性能较好,可以作为防雾包装薄膜使用。

    Abstract:

    Objective The surfactant polyglycerol fatty acid ester (PGFE) was used for surface modification of biaxially oriented polypropylene film (BOPP) to perfect antifogging performance. Methods Used PGFE as an antifogging agent to prepared PGFE/BOPP antifogging film using a coating method. The present study was conducted to investigate the influence of different levels of PGFE on the antifogging performance, mechanical, optical, air and moisture permeability of BOPP film. Results Different levels of PGFE were coated on the film increased its tensile strength and haze, but reduced its light transmittance, oxygen permeability and water vapor permeability. The results showed that the PGFE/BOPP film has a perfect potential for application as an antifogging packaging film, which depicts along lasting antifogging performance, high-quality mechanical stability when the content of PGFE is 2%.
