A disposable wristband prevents damage to information printed on a surface even when being in contact with a drug such as alcohol. The disposable wristband may include a band body made of a fibrous material and having a predetermined length so as to be wound around a user's wrist in a band shape, a thermal label paper provided on a front surface of the band body, and an adhesive member provided on a rear surface of the band body. The thermal label paper may be processed with UV coating. The band body may be made of a nylon cloth material and may have front and rear surfaces dip-coated with polyamide. The adhesive member may be a double-sided tape and provided with a release paper. An apparatus for manufacturing the disposable wristband is also provided.
