Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a composition for a cap liner material and to provide a cap which are excellent in sealability, openability and moldability, can prevent wax float because of extremely little elution of plasticizers, and the like, into contents and are safe for food sanitation reasons. SOLUTION: The composition comprises 5-65 wt% of a polypropylene polymer, 30-90 wt% of a hydrogenated styrene-conjugated diene block copolymer (B) and 5-65 wt% of polyethylene wax (C) with a viscosity average molecular weight of 500-10,000 and a melting point of 90-125°C, and optionally comprises, based on 100 pts. wt. of the sum of the above components, 0-100 pts. wt. of a polyethylene resin (D) and 0-30 pts. wt. of liquid paraffin (E).
