摘要： The present invention relates to an olefin polymer and a preparation method thereof. The olefin polymer exhibits excellent mechanical strength and high processability, and thus is expected to be utilized as a material for various products. Particularly, the olefin polymer can be stably produced into films by a melt-blowing process and thus is expected to be usefully used as a material for products prepared by a melt-blowing process.

摘要： 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.
