PROBLEM TO BE SOLVED: To provide a cap liner material composition wherein an amount of a slip agent to be added to the composition can be reduced and disturbance to a flavor of bottle contents such as a beverage can be prevented by providing a cap liner which is excellent in surface slipperiness. SOLUTION: This cap liner material composition comprises (A) 15 to 80 wt.% of a polyethylene-based resin, (B) 10 to 60 wt.% of hydrogen added styrene-conjugated diene block copolymer rubber with solution viscosity of 100 to 10,000 mPa.s and (c) 10 to 50 wt.% of liquid paraffin with viscosity of 20 to 550 mm2/S (40 deg.C), wherein the composition whose morphology is such that the polyethylene-based resin (A) is a matrix is used. |
