<p>PURPOSE: A manufacturing method of a polyolefin resin is provided to obtain a polyolefin which is excellent in a full notch creep test and is suitable for molding a medium blow-molding by excellent processability. CONSTITUTION: A manufacturing method of a polyethylene resin comprises: a step of preparing a low molecular weight ethylene polymer by reacting an ethylene monomer and a catalyst under the presence of a supported metallocene catalyst in a first reactor; a step of discharging gas by transferring a slurry mixture which contains the low molecular weight ethylene polymer to a flash vessel; and a step of reacting the slurry mixture and ethylene monomer under the presence of a chain propagation agent in a second reactor to manufacture a high molecular weight ethylene polymer.
