一般用激光、超声波完美封边，可用于擦拭敏感表面，产尘量低且摩擦不脱纤维，有良好的吸水性及清洁效率。产品采用18MΩ超纯EDI纯水清洗，在最先进的100级无尘室里包装；四边采用激光、超声波封边，毛、纤维减少、落尘量低、离子释出量低，产品的清洗和包装均在超净车间完成，擦拭后产品不会留下微粒和线头，除污能力强，柔软不会损伤物体表面，特适用于无尘净化车间。
无尘布切割方式
A.激光切割:通过激光瞬间高温融断,封边较好不会产生掉毛屑现象,切割完做清洗等洁净处理,从而使产品达到较高的无尘标准，目前市场经济实用的封边方式。
B.超声波封边:通过超声波振动部组（振子）所产生的振动（让电能转换成机械能），经过HORN（焊头）传递热量，再通过刀具挤压断面料,这种封边是目前无尘布切割方式中最完美的一种,封边效果好且边不会硬,但是此种切割方式成本过高，所以目前只有高端产品会选用。
