Abstract: The present disclosure provides a polyolefin-based film including an olefin polymer which is controlled in the content of the branched polymer structure in the polymer and the weight average molecular weight of the main chain in the structure to exhibit excellent processability and transparency. Therefore, the polyolefin-based film not only exhibits high transparency independent of processing conditions, but also reduces the increase in film haze even when the thickness of the film increases.

Abstract: The present invention relates to ethylene-1-hexene-1-butene terpolymer and a film including the same. The ethylene-1-hexene-1-butene terpolymer according to the present invention has an optimized range of density and melt index and includes 1-hexene and 1-butene as comonomers, and can provide a polymer showing excellent properties by regulating the content ratio of the comonomers in a certain range. Therefore, the film prepared by using the same can be usefully used because it has excellent stickiness, processibility, and falling dart impact strength which are especially suitable for stretch films.
