A polyolefin base resin composition (A) comprising [I] a 1-butene base polymer in an amount of 1 to 99% by weight, [II] a propylene base resin in an amount of 99 to 1% by weight and a nucleus-forming agent in an amount of 10 ppm or more, wherein [I] the 1-butene base polymer satisfies the requirements of a melting point, a stereospecific index, a molecular weight distribution and a weight average molecular weight. The polyolefin base resin composition (A) provides a film which is excellent in a flexibility and an impact resistance and which rises in a crystal stabilizing rate, and the multilayer laminate in which at least one of outermost layers is constituted from a polyolefin resin composition (B) provides a multilayer film which is improved in a low temperature heat sealing property and a hot tacking property making the best use of an excellent characteristic of crystalline polyolefin.
