Abstract:
A polyolefin film made from a resin composition comprising 25 to 70 weight percent of polyolefin resin and 75 to 30 weight percent of an inorganic filler, wherein the polyolefin resin comprises 40 to 80 weight percent of polyethylene resin and 60 to 20 weight percent of polypropylene, and the polyethylene resin comprises 60 to 98 weight percent of a linear low-density polyethylene and 40 to 2 weight percent of a branched low-density polyethylene, wherein the basis weight of the film is from 15 to 60 g/m2, the tensile elongation at break per 1 g/m2 in a TD direction is at least 12.5%/(g/m2), and the tensile strength per 1 g/m2 is at least 17 g/25 mm(g/m2).
