BOPP薄膜表面张力的测试与分析

Test and Analysis on Surface Tension of BOPP Film

通过添加自主研发的爽滑抗粘连母料制备BOPP光膜、BOPP热封膜(单面/双面)、BOPP消光膜,30 d跟踪期内都出现表面张力值不同程度的衰减,但表面张力值均能维持在38 m N/m及以上。测试BOPP消光膜的基本性能指标表明BOPP消光膜的其他性能没有受到影响,维持了较低的摩擦因数(≤0.30)及较高的表面张力。添加自制母料制备的BOPP薄膜系列产品同时具备高表面张力、低摩擦因数的特点,有利于BOPP薄膜的二次加工使用。

By adding a homemade smooth anti aging masterbatch, BOPP film, BOPP heat sealing film （single/double sided） and BOPP matt film were prepared, period of 30 days to the all in different degree of surface tension attenuation, but surface tension could remain above 38 mN/m. Batch production of BOPP matt film basic performance indicators testing showed that BOPP matt film of the other performance could not affect, maintaining the lower friction coefficient （0.30） or less and higher surface tension. Adding homemade smooth anti aging masterbatch preparation of BOPP film series of products had a combination of the characteristics of high surface tension and low friction coefficient to the benefit of secondary processing and using with BOPP film.
