Abstract: A binding tape is constructed from a binding tape paper, an pressure sensitive adhesive layer formed on one side of the binding tape paper, and a release sheet stuck to the pressure sensitive adhesive layer. The binding tape paper is made from a composite paper which includes a pulp at 30-70 parts by weight and synthetic resin fibers at 30-70 parts by weight, in which the synthetic resin fibers have a fineness of 0.4-3.0 deniers and a fiber length of 3-10 mm. The binding tape is formed by cutting the binding tape paper such that the machine direction of the composite paper is directed to the lengthwise direction of the respective binding tape.
