PROBLEM TO BE SOLVED: To prevent failure in carrying and peeling a mountless label.SOLUTION: In a platen roller 14 for a mountless label which includes a cylindrical elastic body coated on a peripheral surface of a cored bar, a material of the elastic body 23 is formed by mixing silicone into an elastomer base material containing, as an essential component, a mixture of two kinds of thermoplastic elastomer comprising olefin-based thermoplastic elastomer using polypropylene as a hard segment and an ethylene-propylene copolymer or an ethylene-propylene-diene copolymer as a soft segment, and stylene-based thermoplastic elastomer using polystyrene as a hard segment and polybutadiene, polyisoprene or polyolefin as a soft segment. |
