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。
BOPP film, BOPP heat-sealing film (single / double-sided) and BOPP matting film were prepared by adding self-developed smooth anti-blocking masterbatch. The surface tension was attenuated to some extent in the tracking period of 30 d, but the surface tension Values can be maintained at 38 mN / m and above. Testing BOPP matte film basic performance index shows that the other properties of BOPP matte film unaffected, maintaining a low friction coefficient (≤ 0.30) and higher surface tension. BOPP film products prepared by adding homemade masterbatch also have the characteristics of high surface tension and low friction coefficient, which is beneficial to the secondary processing of BOPP films.
