A dispensing unit for a thin film dispenser has a base, a wheel assembly, a thin film and a locking device. The wheel assembly is mounted on the base and has a tape supplying wheel and a used tape collecting wheel. The tape supplying wheel and the used tape collecting wheel are mounted rotatably on the base. The thin film is mounted around the wheel assembly. The locking device is resiliently disposed on the base and selectively engages the wheel assembly to prevent the wheel assembly from rotating. Accordingly, the locking device can provide a locking function to the wheel assembly to prevent a thin film from being loosened during the course of packaging, transporting and assembling processes.
