采用外涂布工艺技术制备了聚丙烯涂覆膜,并将不同浓度的失水山梨醇脂肪酸酯溶液涂覆于聚丙烯薄膜上,测试进行水浴实验之后的涂覆膜的透光率及力学性能,并与未涂膜的透光率进行对比和评价。结果表明：空白聚丙烯膜的透光率为93.24%,涂覆膜的透光率明显提高,当失水山梨醇脂肪酸酯的质量分数为12%时,薄膜的透光率最高,达96.03%;同时,涂层使薄膜的力学性能有不同程度的提高。红外光谱分析结果表明：酯基团在水浴实验时水解可生成亲水基团,改善薄膜的润湿张力,因此薄膜表面涂覆层对透光率的改善起到了较大作用。

The coated PP films were produced by the means of overlaying. In the experiment, the solutions of the sorbitan monooleate with different concentration were coated on the PP films. The light transmittance and the mechanical property were tested after the water bathing, which were compared with the PP films without coating. The results indicate that the light transmittance of the coated films was higher than the films withom coating whose light transmittance was 93.24%. When the concentration of the Sorbitan Monooleate was 12%, the light transmittance was up to 96.03%. In addition, the mechanical property of the coated PP films was raised. The analysis of infra-red spectrum indicated that the ester group could hydrolyze into hydrophilic group during the hydrolyzing. This could improve the surface tension of films. Therefore, the overlay played a big role in the improvement of light transmittance.
