PROBLEM TO BE SOLVED: To provide a polyethylene resin composition useful for a back sheet material and improving tensile strength and elongation characteristics in the back sheet of sanitary goods for increasing separability of the back sheet from underwear after use and improving molding workability.
SOLUTION: The polyethylene resin composition comprises (A) 40-87 wt.% of a linear low-density polyethylene-based resin, wherein density is 0.880-0.930 g/cm
3 while a minimum value among differential values (dN/dS) of an elongation load curve in a tension test is higher than zero, (B) 10-40 wt.% of a branched low-density polyethylene-based resin with an MFR (at 190°C with a load of 21.18 N) less than 6 g/10 min, and (C) 3-20 wt.% of a branched low-density polyethylene-based resin with an MFR of 6 g/10 min or higher.COPYRIGHT: (C)2010,JPO&INPIT
