Abstract
A flat, heat recoverable shrink object is comprised of a plurality of core strands placed in a parallel position and each having a polymeric, thermoplastic or crosslinked core around which is coiled a high tensile strength thread such as glass, metal, cotton polyamide etc. These core strands are combined with high strength threads extending transverse to the core strands and being e.g. interwoven or looped or just superposed; All these parts are embedded in a crosslinked, heated stretched and cooled-again polymer layer whereby the coiled helices are stretched accordingly. This flat object is applied to other objects for being heat shrunk thereon. The two high strength threads tear proof the object particularly during its being made.
