开口爽滑母粒在POF热收缩过程中是必不可少的功能助剂，加入该母料后能防止薄膜在收卷过程中产生粘结，使膜卷在放卷和分切时更畅顺，并且使薄膜在使用过程中具有良好的开口性能。开口母粒适用于添加在薄膜的内外层，爽滑母粒添加于薄膜的中间层，使用量低，体现小身板，大能量的特点。
Opening smooth masterbatch is an indispensable functional auxiliaries in the process of POF thermal shrinkage. The addition of the masterbatch can prevent the film from bonding in the process of coiling, make the coil more smoothly in unwinding and cutting, and make the film have good opening performance in the course of using. Open master batch is suitable for adding in the inner and outer layers of the film, smooth master batch is added in the middle layer of the film, low usage, reflecting the characteristics of small body, large energy.
