Abstract

PURPOSE:To open the inside easily after even a polymer having self-adhesion has been made into a heat-shrinkable tube, by a method wherein a mold release tape is inserted into the tube which is in a process prior to expansion and then the tube is expanded. CONSTITUTION:A mold release tape 2 such as kraft paper or the mold release tape 2 obtained by performing mold release treatment on the surface of the kraft paper with tetrafluoroethylene resin is inserted within the tube 1 molded by extrusion at the time of extrusion molding. Air is fed within the above- mentioned tube 1, the tube 1 is heated at the softening point or higher with a preheating pipe 13, expansion molding is performed with a sizing die 5, pressed by a pinch roller 15 and a flat heat-shrinkable tube 3 having an inner mold release tape 2 is obtained. Even a part which is stuck through adhesion can be opened easily by removing the inner mold release tape 2 by cutting the flat heat-shrinkable tube 3 like this into predetermined lengths.
