    摘要： Disclosed is a liner film for bulk container, which comprises a polyethylene (A) prepared by the use of a single site olefin polymerization catalyst such as a metallocene catalyst, said polyethylene (A) having a density of 0.920 to 0.940 g/cm3, MFR of 0.1 to 3.0 g/10 min and a melting point of 115 to 135° C. When the film is heat-sealed, its sealed portion preferably has a tensile strength at break (Ts) of 2.0 to 4.0 kg/15 mm and a tensile elongation at break (EL) of 150 to 600%. The liner film for bulk container has the advantages: the film can be made lightweight by decreasing the film thickness; the film shows such a high heat-sealing strength that the heat-sealed portion is not broken even if no adhesive tape is attached thereto; and a bulk container liner formed from the film can be filled with a content of a higher temperature than the conventional temperature. Also disclosed is a bulk container liner shaping the above film into a bag.
