Polyolefin

The present invention relates to polyolefin. More specifically, the present invention relates to polyolefin having excellent dart drop impact strength, and exhibiting improved transparency, and such polyolefin has a density of 0.915 g/cm3 to 0.930 g/cm3 measured according to ASTM D1505; and satisfies the following requirements (provided that S1+S2+S3=1), when measuring the relative content of peak area according to melting temperature (Tm) using SSA (Successive Self-nucleation and Annealing) analysis: the content(S1) of peak area at Tm less than 100&#xb0; C. is 0.33 to 0.35; the content(S2) of peak area at Tm of 100&#xb0; C. or more and 120&#xb0; C. or less is 0.52 to 0.56; and the content(S3) of peak area at Tm greater than 120&#xb0; C. is 0.10 to 0.14.

The present disclosure relates to a polyethylene resin composition exhibiting excellent processability and bubble stability, which can provide a film or fiber having excellent physical properties through various processes. The polyethylene resin composition includes a first polyethylene resin having a density of 0.950 g/cmto 0.960 g/cm, a weight average molecular weight of 80000 g/mol to 100000 g/mol and a molecular weight distribution of 3.3 to 4.0; and a second polyethylene resin having a density of 0.950 g/cmto 0.960 g/cm, a weight average molecular weight of 500000 g/mol to 600000 g/mol and a molecular weight distribution of 1.3 to 2.0.
