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.
