PROBLEM TO BE SOLVED: To provide a polyolefinic resin composition that is prevented from the generation of a die build-up in molding it and improves the continuous operationability of extrusion molding. SOLUTION: The polyolefinic resin composition is formulated with 0.02-0.5 pts.wt. of an alkali metal salt of an 8-28C higher fatty acid based on 100 pts.wt. of a polyolefinic resin. The composition reduces adherence of the die build-up to a die lip at the time of molding and can prevent skin roughing (melt fracture) of the molded product, discontinuity of the film, the generation of burned foreign matter and the like.
