The invention provides a film and a preparation method thereof; the film mainly is prepared mainly from a solubilizing type ultra-high molecular weight ultrathin propene polymer; the viscosity average molecular weight (Mv) of the solubilizing type ultra-high molecular weight ultrathin propene polymer is more than 1x10<6>; the solubilizing type ultra-high molecular weight ultrathin propene polymer contains spherical particles, the mean particle size is 10 Mum-200 Mum, a standard difference is 2 Mum-15 Mum, and bulk density is 0.1 g/mL-0.4 g/mL; a solvent in the solubilizing type ultra-high molecular weight ultrathin propene polymer is more than 0 and less than or equal to 98% by weight. Since the solubilizing type ultra-high molecular weight ultrathin propene polymer is applied as the raw material, the film is excellent in creep resisting performance and extremely wide in temperature scale. Besides, the film has excellent physical and thermal properties, and is applicable to a battery diaphragm.
