Zusammenfassung: | A process for the production of a heat-recoverable wraparound closure article having a closure means along at least one of a pair of opposed edge regions thereof which includes the steps of bonding parts of a body of fusion bondable polymeric material which is or may be rendered heat-recoverable, to a substrate or fusion bondable polymeric material to produce the configuration of the said closure means and cross-linking the bond-forming parts of the body and the substrate to each other. This provides a highly efficient method of producing "rail and channel" wraparound closures with closure rails durably bonded to a heat-recoverable wraparound sheet. |
