1. A polyolefin resin satisfying following properties (1) to (6):
(1) melt index (MI2.16, 190° C., under a load of 2.16 kg) is 0.1 to 1.5 g/10 min;
(2) density is 0.91 to 0.93 g/cc;
(3) polydispersity Indexe (weight-average molecular weight/number-average molecular weight (Mw/Mn)) is 3 to 7;
Z-average molecular weight/weight average molecular weight (Mz/Mw) is 2.3 to 4.5;
(5) Comonomer Orthogonal Index (COI) value calculated by the following Equation 1 is 5 to 12; and
(6) when a temperature rising elution fractionation (TREF) curve of multimodal distribution is deconvoluted, an area of the TREF curve having a peak at 60 to 70° C. is 40 to 65% of a total area of the TREF curve of multimodal distribution,
in Equation 1, “SCB” represents an average number of short chain branches, “SCB number at Mz” represents average number of short chain branches derived from comonomers per 1000 carbon atoms at Z-average molecular weight (Mz), and “SCB number at Mn” represents average number of short chain branches derived from comonomers per 1000 carbon atoms at number-average molecular weight (Mn) when a molecular weight-comonomer distribution graph was prepared in which log value (log Mw) of molecular weight (Mw) is marked in x-axis of the graph and the amount of polymer (dw_dlog Mw) corresponding to the log value (log Mw) and average number of short chain branches (SCB) derived from comonomer (number of branches per 1,000 carbon atoms, unit: number/1,000 C) corresponding to the log value (log Mw) are marked in y-axis of the graph, and wherein melt flow rate ratio (MFRR; MI21.6/MI2.16, the MI21.6 is a melt index measured at 190° C. and 21.6 kg load condition) is 17 to 40.
