A heat recoverable, shrink-object is made from a mesh or web assembly having thermoplastic threads that extend in a first direction, and second threads that are essentially non-stretchable and run transversely to the first threads, that assembly is embedded in a polymer matrix which is then crosslinked; the thermoplastic threads do not crosslink; the matrix with embedded mesh or web is then heated to a temperature above the crystallite melting point of the polymer matrix and the thermoplastic threads are stretched into an elongated state at that temperature, and the stretching is maintained during subsequent cooling until a lower temperature including room temperature is reached and stretching is no longer needed to maintain said elongated state.
