Abstract:
An object of the present invention is to provide a polyethylene-based resin composition excellent in the moldability and at the same time, excellent in the balance between impact strength and stiffness as well as in the transparency, and a molded product and a film, which are obtained by the molding of the polyethylene-based resin composition. The polyethylene-based resin composition of the present invention comprises from 41 to 99 wt % of (A) an ethylene-based polymer satisfying specific conditions and from 1 to 59 wt % of (B) an ethylene-based polymer satisfying specific conditions, wherein MFR of the composition as a whole is from 0.05 to 50 g/10 min and the density is from 0.910 to 0.960 g/cm3.
