<P>PROBLEM TO BE SOLVED: To provide a heat-resistant liner for a metallic PP (pilfer proof) cap, having good moldability, without causing a wax float phenomenon, having heat resistance and impact resistance, capable of being effectively prevented from leakage, and having good openability, and to provide the cap with the liner, and to provide a method for producing the same. <P>SOLUTION: This heat-resistant liner for the metallic PP cap is formed out of a resin composition for the liner which contains (E) 0.1-20 pts.wt. of finely-powdered talc having an average particle diameter of 0.1-10 μm based on 100 pts.wt. of a resin composition comprising (A) 30-50 wt.% of a hydrogenated styrene/conjugated diene-based block copolymer having a melt flow rate of 0 at 230°C with a load of 21.18 N (2.16 kgf) (i.e., the copolymer does not flow under the condition), (B) 35-50 wt.% of liquid paraffin, (C) 5-30 wt.% of a polypropylene-based resin, and (D) not less than 0.2 wt.% of a silicone oil [provided that each of the wt.% is based on a total amount of the components (A), (B), (C) and (D)]. The cap with the liner and the method for producing the same are provided, respectively. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
