METHOD FOR PRODUCING PROPYLENE-BASED MAT FILM

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a propylene-based mat film by which even a propylene-based thin mat film can continuously be produced as good as a thick film thereof by extrusion. SOLUTION: This method for producing the propylene-based mat film is composed of extruding a resin composition comprising a mixture of isotactic polypropylene resin and syndiotactic polypropylene resin as a main component in a film state and applying to a mat-emboss by using a silicone roll and especially composed of using the resin composition having (95:5) to (5:95) mixture ratio of the isotactic polypropylene resin and the syndiotactic polypropylene resin.
