The present invention relates to a tension wound roll of tape. The tape does not contain a separate adhesive layer but will bond to itself after being elongated by at least 50 percent and wrapped in overlapping layers. The tape of the invention will not self fuse when in roll form. The present tape is prepared from a minor proportion of a thermoplastic polymer and a major proportion of elastomeric polymer, and further contains a minor amount of an anti-blocking agent. The tape may be used in a wide variety of applications, for example, to repair leaks in hoses or pipes.
