ABSTRACT:
A method of manufacturing a labeled container of synthetic resin having a label affixed to its outer periphery. A heat-stretchable tubular label is inserted into a forming die, and a thermoplastic resin sheet which has been heated and softened is positioned within a space defined by the label. When the resin sheet is expanded radially of the tubular label, the resin sheet is expanded radially under heat simultaneously with the resin sheet, so that both the resin and the label are formed into a shape conforming to the internal surface configuration of the forming die.
