The invention relates to a polyethylene binder. Namely, a press machine which is heated to 150 DEG C is used for obtaining a thickness of 0.1 mm. 4.1 cc/cm /s air-permeable 75 g/m polyester non-woven fabric is bonded at a pressure of 10 Mpa for 15 seconds, and the bonding strength measured on the basis of ASTM D 903 is 405 gf or more; wherein in the formula 1, Iash is based on 10 g of polyethylene, and after the polyethylene stays at the temperature of 650 DEG C for 1 hour, the total weight percentage of inorganic matter components contained in ash is met, and Iash is smaller than or equal to 40%. 本发明涉及如下的聚乙烯粘结剂，即，使用加热至150℃的压力机对具有0.1mm的厚度、4.1cc/cm/s的透气性的75g/m的聚酯无纺布以10Mpa的压力进行粘结15秒钟后以ASTM D 903为基准测定的粘结强度为405gf以上，满足式1：0重量百分比<I≤40重量百分比，在上述式1中，I为以10g的聚乙烯为基准，在650℃的温度下停留1小时后，灰分中含有的无机物成分的总重量百分比。
