PROBLEM TO BE SOLVED: To provide a polyolefin resin composition which is excellent in transparency and has little decrease in transparency under high-temperature and high-humidity atmosphere, and a polyolefin resin composition obtained therefrom and suitable for optical products and medical and pharmaceutical molded articles. A resin molded article is provided. SOLUTION: The polyolefin resin composition has a thickness of 3%. The degree of crystallinity is 0% or less according to ASTM D1003, the total light transmittance is 80% or more, and the water absorption is 0.1% or less when immersed in water at 23 ° C. for 100 hours. It comprises up to 20% of a polyolefin resin and a specific sorbitol derivative. Further, the polyolefin-based resin composition comprises a cyclic olefin-based polymer composed of a cyclic olefin having a specific structure, and the sorbitol-based derivative. The polyolefin resin molded article is formed by various molding methods using the resin composition. |
