Abstract
The present invention relates to an olefin-based polymer, which has (1) a density (d) ranging from 0.85 to 0.90 g/cc, (2) a melt index (MI, 190° C., 2.16 kg load conditions) ranging from 0.1 g/10 min to 15 g/10 min, (3) the density (d) and the melt temperature (Tm) satisfying Tm (° C.)=a×d−b of Equation 1 (2,350<a<2,500, and 1,900<b<2,100), and (4) a ratio (hardness/Tm) of the hardness (shore A) to the melt temperature (Tm) in a range of 1.0 to 1.3. The olefin-based polymer according to the present invention exhibits excellent anti-blocking properties due to having improved hardness as a low-density olefin-based polymer.
