ABSTRACT:
A dental tape is constituted by a length of incipiently fibrillatable plastics film. The tape may be made by extruding a polypropylene film in strip form onto chilled take-off rollers and then roll embossing the film by means of hardened steel rollers. After embossing, the film is oriented by means of draw rollers.
In an alternative embodiment, the tape is made by partially fibrillating a plastics film by means of a spiked roller, followed by drawing to orient the film.
The dental tape may be contained in a hand-held dispenser.
