Multimodal polyolefin resins for manufacturing films, pipes, hollow molded articles having high melt strength and excellent formability, mechanical strength, processability and appearance are described. The resins have: density is 0.930-0.960 g/cm; melt flow index is 0.01-10.0 g/10 minutes; ratio Mw/Mn is 10-60; and two or more peaks appear when molecular weight is measured by GPC. In molded pipe, the Mw of polymer collected at position B is 0.1% greater than Mw of polymer collected at position A; polymer having Mw of 10,000 or less among polymers collected at position A is 0.1% greater than the amount of polymer having Mw of 10,000 or less among polymers collected at position B; and the amount of polymer having Mw of 1,000,000 or more among polymers collected at position B is 0.1% greater than the amount of polymer having Mw of 1,000,000 or more among polymers collected at position A.
