Resin Composition And Use Thereof

Abstract: The purpose of the present invention is to obtain a resin composition that exhibits good high-speed moldability, has low adhesion to a chill roller or guide roller at the time of film formation, and exhibits excellent adherence to a polar group-containing resin (polar resin). The present invention relates to a resin composition including: 75-100 parts by mass of a propylene-based polymer (A); and 0-25 parts by mass of a copolymer (B) that satisfies prescribed requirements and is composed of ethylene and at least one type of a-olefin selected from among a-olefins having 3-20 carbon atoms [where the total amount of (A) and (B) is 100 parts by mass]. At least part of the propylene-based polymer (A) is modified by a polar compound. The resin composition satisfies prescribed requirements.
