PROBLEM TO BE SOLVED: To provide a soft-touch tape strip having a superior adaptability against a tensile strength or a tape strip applicator machine. SOLUTION: This tape strip comprises a single synthetic resin layer made of polypropylene with a width 20 to 80 mm and a thickness 0.08 to 0.25 mm. This synthetic resin layer is a tape strip monoaxially extended with a draw ratio 3 to 8 times, and preferably polypropylene has block copolymer 50% or more. It has a high tensile strength, no longitudinal crack, less curved state and so it has a superior adaptability with a tape strip applicator. COPYRIGHT: (C)2006,JPO&NCIPI
